A regular polygon.
No, it is not true that in a polygon all sides and angles are congruent. A polygon with all sides congruent is called a regular polygon, but there are also irregular polygons where the sides and angles can vary. For example, a rectangle has congruent opposite sides but not all sides are equal, and its angles are congruent but not all angles need to be equal in other types of polygons. Thus, congruence in sides and angles only applies to regular polygons.
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.

It is called an irregular polygon. However, an irregular polygon can have congruent sides if all angles are not equal.

It would be an irregular polygon that has not congruent sides and angles
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 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.
