Question

Bob and Sally decorated their living room walls with paper polygons - all were regular 6-sided polygons.

Degrees in a 3 to 8 sided figure:
Sum of angle measure = 180(n - 2),
where n = number of sides


A. What is the total number of degrees in the interior angles of a regular 6-sided polygon? Show or explain all your work.

B. What is the measure of 1 interior angle of this same polygon? Show or explain all your work.
