# Hexagon Interior and Exterior Angles: Quick Exploration

## In the Geometry app below,

1) Use the POLYGON tool to construct hexagon

*ABCDEF*. 2) Select the ANGLE tool. Then click anywhere inside the polygon. 3) Go to the Algebra view (click calculator icon upper left). 4) Calculate the**sum of the measures of the interior angles of this hexagon**, making sure to add the Greek letters (and not single numerical values)! If you forget how to do this, click here to see it again in the context of a triangle.Select the MOVE tool in the app above. Move any one (or more) of the triangle's vertices around. What can we conclude about the **sum of the measures of the interior angles** of any hexagon?

## Here, in this app, we have a hexagon with its EXTERIOR ANGLES shown. Calculate the SUM of the measures of these exterior angles here in this app.

Select the MOVE tool. Move any one (or more) of the triangle's vertices around.
What can we conclude about the **exterior angles** of this hexagon? *Be specific in your response. *
