Area
3 part question: How do you find the area of a square? A triangle? A polygon?
Bonus 50 points: How do you where the height is on a polygon?
Square: L x W
Triangle: 1/2 B x H
Polygon: B x H
How do you find the surface area of a polyhedra?
Find the area of each face and add them together.
When classifying a polyhedron, what is the difference between a prism and a pyramid?
Prism: Two bases that are parallel, naming based on the shape of its base (ex. triangle bases is a triangular prism)
Pyramid: One base. Every side must be a triangle besides base.
Bonus if you write it in exponent form too.
