Investigation 2.1 Notes

**The focus question is: ***What is the size of each angle and the sum of all angles in a regular polygon with n sides?*
The students will review what is important in a polygon and how regular and irregular polygons compare. The goal is for students to develop formulas the sum of interior angles for a polygon of n sides.
S - Sum of all angles

S = 180 (n - 2)
when n = any number of sides of a polygon

A - measure of one angle

A = 180 (n - 2)/ n
ORA = 180 - 360/n
when n = any number of sides of a polygon
