Problem: Let be the sum of the interior angles of a polygon for which each interior angle is times the exterior angle at the same vertex. Then
Answer Choices:
A. and P may be regular
B. and P is not regular
C. and P is regular
D. and is not regular
E. and P may or may not be regular
Solution:
Since each interior angle is times its associated exterior angle, (sum of the exterior angles)
Since
A -sided polygon that is equiangular may or may not be equilateral, and, hence, regular.
