TOPIC:  Polygons

GOAL:  Classify polygons, triangles and quadilaterals. 

STANDARDS: 

• 7.G.5

• Use facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure.

• 8.G.5

• use informal arguments to establish facts about the angle sum and exterior angle of triangles, about the angles created when parallel lines are cut by a transversal.

How are diagonals connected to angle measurements?
