Theorems

All we did today was a Must Know, find the area of a trapezoid, and find a Theorem for every more sided polygons. Today us students were able to develop a theorem to find the sum of angle measures of adding polygons. The theorem was (n-2)180. The area of a trapezoid is (b1+b2) or 1/2 (b1+b2)h. The must know
