Draw a pentagon, a hexagon, and a heptagon.
What is a polygon?
What do you think a CONVEX polygon is?
What theorems do I need today?
Let's do some examples!
What is the sum of the interior angle measures of a heptagon?
What is the measure of angle Y?
What is the measure of angle G?
What is the measure of angle 1 in this regular polygon?
Try these with a neighbor:
Find the sum of the interior angles of an 11-gon
Find the measure of one exterior angle of a regular 12-gon
Find the measure of one interior angle of a regular 18-gon
