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
