The interior angle measure of a regular polygon is calculated with the following formula, where n represents the number of sides or interior angles of the regular polygon.

Interior Angle = 180 (n-2) / n

A. Determine the measure of the interior angles of a regular decagon. In your answer, include all calculations.

B. Use your result from part A to identify whether or not a regular decagon can be used as the only shape in a regular tessellation.

N would be equal to 10, so 180 (10-2) / 10, simplifying to 180 (8) / 10, further to 18 (8) = 144 degrees, so no it would not tessellate
