Question

A figure is said to be regular if its sides are equal in length and angles are equal in measure. Can you identify the regular quadrilateral?

Answer 1

Hint: There are figures of quadrilateral which have equal sides and equal angles, but difference in one property.

Complete step-by-step answer:
A quadrilateral with
All sides equal
All angles are equal

That is a SQUARE/Rhombus.
If it is a SQUARE:
It has all sides equal.
It has equal angles
Its diagonals are equal

If it is RHOMBUS:
It has all sides equal.
It has equal angles
Its diagonals are not equal
So it can be either SQUARE or RHOMBUS.

Note: There are many regular polygons in Quadrilateral but each polygon has different properties, by understanding these properties anyone can identify the shape.
