Question

Which of the following are definitely regular polygons?

• A. Triangle
• B. Square
• C. Rectangle with unequal sides
• D. None of these

Answer 1

The correct option is B

Square

A regular polygon is a polygon which is equiangular i.e. all the angles are equal and equilateral i.e. all the sides are equal.

The triangle if equilateral is a regular polygon. If not, it is not a regular polygon.

A rhombus has equal sides but not equal angles.

A Rectangle has equal angles but not equal sides. Hence, they are not regular polygons.

A square has equal sides and equal angles. Hence, it is a regular polygon.
