no choice theorem- if two angles of one triangle are congruent to two angles of a second triangle, then the third angles are congruent.
AAS- if there exists a correspondence between the vertices of two triangles such that two angles and a non-included side of one are congruent to the corresponding parts of the other, then the triangles are congruent

1. I can apply theorems about interior angles, exterior angles and midlines of triangles.
2. I can apply the No Choice theorem.
3. I can use some important formulas that apply to polygons.
4. I can recognize regular polygons.
5. I can use a formula to find the measure of an exterior angle of an equiangular polygon.
