Question

An ..................... polygon has sides of any length and angles of any measure.

• A. regular
• B. supplementary
• C. triangular
• D. irregular

Answer 1

The correct option is D irregular

A regular polygon is equilateral(sides of equal length) and equiangular(angles of same measure).

The angles of a polygon are supplementary when the measure of interior and exterior angles is ${180}^o$.

In triangular polygon, the sum of its three angles is ${180}^o$.

And, an irregular polygon has sides of any length and it has each interior angles of any measure.

Therefore, option D is correct.
