They are known as regular polygons.
Polygons have an equal number of sides and angles.
two polygons with sides that have all equal sides and angles
Convex polygons with congruent sides and congruent angles are called regular polygons.
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.
All polygons have an equal number of sides and angles.
They are called regular polygons
Most irregular polygons.
Yes
Yes in general polygons that have equal interior angles also have equal sides and they are said to be regular polygons. But a rectangle is an exception.
Polygons
A regular polygon has all sides equal and all angles equal.
