Hey Everyone, hope you like my growing post :). Just to let you know:
Pink= The Questions asked
Black= The Information

Red= Example Questions

Blue= The work shown for each Example Question

*Colour may vary

Question #1: What is the Pythagorean Theorem? You should use words, pictures, symbols and numerical examples.

The Pythagorean Theorem was developed by a Greek mathematician, Pythagoras. The Pythagorean Theorem is used to find lenghts of the sides of any right triangle. Area of a square = length x width
Pythagoras treated each sides of a right triangle as though it were a square and discovered that the total area of the two smaller squares then wrote his discovery as a formula.
Two special triangles
Isosceles right triangle

So what is the formula that Pythagoras came up with?
Well, its simple : use the formula to find the hyponuse or either two of the legs.

The picture above: is of Pythagoras on snoopy's body teaching William Hung about the Pythagorean Theorem. *William Hung was not alive at the time of Pythagoras just so you know!

1)A right triangle has a hypotenuse or 30 and a base of 20 what is the missing leg?

2) A right triangle has a base of 5 and a leg or 15, what is the missing hypotenuse?

Question #2: How do you find the surface area of a right rectangular prism? You should use words, pictures, symbols and numerical examples.

A rectangular prism is a three dimentional shape where all the sides are rectangles and all sides meet perpendicularly. The bases are congruent with eachother. Cereal boxes and bricks are rectangular prisms.
To find the surface area of the examples above: the cereal box and the brick. Measurments will have to me made. Plug the measurements into the formula and solve.
To the left, is an example of a rectangular prism. and examples of its length and height which are important when solving for volume and surface area.

To find Surface area, use the following formula: SA=2(l*w)+2(l*h)+2(h*w)
The formula for finding Volume:V=l*w*h
Example of Surface Area:
A Rectangular Prism has a lenth of 23m a width/depth of 13m and a height of 12m. What is the surface area?

Example of Volume:

Find the volume of a rectangular prism if the length is 23 the width/depth is 13 and the height is 12.

Surface area and Volume is helpful when it comes do designing a home, room, or painting a room or a whole house.

Question #3: How do you find the surface area of a right cylinder? You should use words, pictures, symbols and numerical examples.

A three dimentional shape made of parallel segments to a line of two parallel pnales conected to congruent bases that are circles in the planes. Examples include pillsbury crescents in a tube and some certain trash cans are cylinders.

To find the surface area, first find the measurements then plug them into the formula and solve.
To the right, is an example of cylinders with the radius which is extremely important to use when solving anything involving a cylinder or a circle.

To find the Surface area of a right cylinder, use the formula: The formula may be hard to use at first, once it is used more often it will become familiar therefore making it memorized.

Question #4: What is a polygon and how do we classify one?

A polygon is a shape that is closed up that has at least around three lines. Regular polygons are made up of same symmetric lines, angles and length. Irregular polygons are made up of non symetric lines.

Here on the right are some examples of a polygon. Ex. octagon, hexagon, decagon, nonagon, square and other shapes that is closed up.

Shape are everywhere in the world!

Dr. Pepper is a drink, that takes the shape of a cylinder, it has a length and a radius. By finding the measurements for the can, the circumference, diameter, and radius of the circles on the top and bottom can be found. The Surface are and Volume can be found my using the formulas on Question# 3.

Babybel cheese, is a circle. it has a circumference and a diameter. Measure the diameter,<----------> and then find the radius <---- which is half or the diameter.

The Kraft dinner box, is a rectangular prism. It has a height, a width, and a length all it takes is a ruler to measure it and solve for the Volume and Surface area by using the simple easy formula as shown in Question# 2.

Just for fun!: As an experiment look around the house for shapes and try to find the volume, surface area, perimeter, area, and etc. If you get lost, simply review the questions and formulas and try again. Good Luck!!!

Question 1: What is the Pythagorean Theorem? You should use words, pictures, symbols and numerical examples.

What is the Pythagorean Theorem? Well my friends, it’s a formula. The formula is a² + b² = c² . That means altitude squared plus base squared is equal to the hypotenuse squared. The side that is opposite of the right angle is the hypotenuse. The base and altitude are the other two, but they’re also called legs.

A= Altitude
B=Base
C=Hypotenuse

Now lets just say that A is 10 cm,

B is 10 cm, and you're solving for c.
Well you would go:
a² + b² = c^{2
10 2 + 10 2 = c 2
100 + 100 = c 2
200√ = c
c= 14.2}







Now we're solving for B instead of C ! Yes...quite intense. But, don't be scared, it's just as easy:) alrighty, so first try to think it out on ur own without looking at the answers............ okay, now I'll work you through it. So now since you are trying to figure out what B is, you would go C2-A2=B2.
So we know that C is 9 and A is 8. So 9 squared is 81, 8 squared is 64, therefore we have 81 - 64 = C 2. Now, 17 = B 2. Then you get the square root of 17 ! which is 4.2 . And then BAM ! B = 4.2 CM !!! Its super fun once you get the hang of it ! :)






Question 2: How do you find the surface area of a right recta ngular prism? You should use words, pictures, symbols and numerical examples.

A right rectangular prism is a six sided rectangle with all right angles, like a cube, but longer. Now lets find the surface area. The formula is:

SA= 2 ( L x W ) + 2 ( L x H ) + 2 ( W x H )

soo.....

SA= 2 ( 6 x 4 ) + 2 ( 6 x 6.5 ) + 2 ( 4 x 6.5 )
SA= 2 (24) + 2 (39) + 2 (26)
SA= 48 + 78 + 52
SA= 178 cm

HOW COOL ?! ;)

Question 3: How do you find the surface area of a right cylinder? You should use words, pictures, symbols and numerical examples.

A right cylinder is basically just a tube, with a circle on both ends, like a can, or a jar.The Formula is 2πR 2 + 2πRH















These lipsticks are all cylinders ! :)

Question 4: What is a polygon and how do we classify one?

A polygon is simply a shape made up of three or more straight lines that all connect. A regular polygon has sides that that are all the same size, and it has as many sides as vertices. An irregular polygon is just the opposite; sides with different lengths are angles. IT'S SIMPLE !

Question 1: What is the Pythagorean Theorem? You should use words, pictures, symbols and numerical examples.

A right angle triangle has a base, altitude, hypotenuse and a right angle.

The Theorem of Pythagoras, (which was named after the famous mathematician Pythagoras), is a formula that is written as a² + b² = c². The a represents the altitude, the b represents the base and the letter c represents the hypotenuse.

This formula states that the altitude squared, plus the base squared, equals the hypotenuse squared of a right angle triangle. (This formula only works on right angle triangles!)

Now, let's solve an equation with a missing hypotenuse. Don't worry, if you use the formula correctly this equation should be easy.

Let's solve one more equation, except this time, the equation will have a missing leg, (altitude or base), instead of the hypotenuse. This may seem tricky, but if you use your knowledge of algebra, it should be a piece of cake!

Question 2: How do you find the surface area of a right rectangular prism? You should use words, pictures, symbols and numerical examples.

You may not realize it, but we see right rectangular prisms everywhere during our everyday lives. Some examples include....

Cereal Boxes

Speakers

DVD Players

Jewellery Boxes

You can easily find the surface area of a right rectangular prism by using the following formula:

SA = 2 (lw) + 2 (lh) + 2 (wh)

This is a net of a right rectangular prism. When it is folded correctly, it creates a rectangular prism.

Using the rectangular prism I made and its dimensions, let’s figure out its surface area.

SA = 2 (l h) + 2 (h w) + (l w)
SA = 2 (15 8) + 2 (8 5) + 2 (15 5)
SA = 2 (120) + 2 (40) + 2 (75)
SA = 240 + 80 + 150
SA = 470 m²



Question 3: How do you find the surface area of a right cylinder? You should use words, pictures, symbols and numerical examples.

A cylinder is a solid that has two parallel, congruent circular bases. We actually see cylinders everywhere around us. Here are some examples of cylinders you might be familiar with:

Soup Cans

Frozen Juice

Pop Cans

Here is a picture of a cylinder and its dimensions.

This is what the cylinder above, would look like if it was flattened out. This is called the cylinders’ net.

Finding the surface area of a cylinder is quite simple, if you use the correct formula. The formula is:

SA = 2п r² + 2п r

Using the same cylinder, let’s figure out how to find the surface area.
SA = 2п r² + 2п r h
SA = 2 (3.14) 5² + 2 (3.14) (5) (12)
SA = 2 (3.14) 25 + 6.28 (60)
SA = 157 + 376.8
SA = 533.8 cm²

Question 4: What is a polygon and how do we classify one?


A polygon is classified as any closed figure that has three or more straight line segments.
