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 !
