Regular polygons have congruent sides and angles
A regular pentagon
That would be called a regular polygon, one with congruent(equal) side legnths and congruent angles.
a regular polygon
A four-sided polygon with four congruent sides and four equal angles is a square
It is called an irregular polygon. However, an irregular polygon can have congruent sides if all angles are not equal.
an irregular polygon
A polygon that has congruent sides and congruent angles is called a Regular polygon. If the number of sides is given, you can be more specific. Some examples: 3 congruent sides/angles = equilateral triangle 4 congruent sides/angles = square 5 congruent sides/angles = regular pentagon 6 congruent sides/angles = regular hexagon ...and so on, by adding "regular" in front of the shape's name.

A regular pentagon
A regular polygon is a polygon with congruent sides and interior angles.
It is called a regular polygon. * * * * * Actually not. All its angles must also be congruent for it to be called regular.

A square
All its angles are of the same measure and all its sides are congruent.
