The ins and outs of polygons

Interior angle: The angle inside a polygon formed by 2 adjacent sides of a polygon. (the angles inside the figure)
-Jacks ideas: (# of sides-2) x 180= sum of anterior angles 
-Delany's: (# of sides x 180) -(180x2)= sum of anterior angles 

Exterior angle: Are measured by extending a side of a convex polygon and measuring the angles that lie outside the line. 

-The sum of all exterior angle measures is 360. 

*What is the relationship between interior and exterior angles? 
-They are supplementary: If you add them together they equal 180. 


Label the exterior angles and the interior angles. 

Predict: 
What would be the sum of all the angles? 

Track problem: 
What is the sum total of those left turns? No math, make a reasoning as to what it is going to be. 

As there are more sides, the shapes become more circular.
