No only regular polygons have congruent angles.
All regular polygons with an even number of angles. All the angles of polygons with an odd number of angles are also equal but there are no "opposite" angles.
Angles cannot be equiangular: the latter is a property of polygons. Equiangular polygons are ones in which all the angles are equal.
No.
Regular polygons are when all the sides are same length and all the angles are the same size. Irregular polygons are shapes where the sides are not all the same and the angles are different.
They are known as regular polygons.
Exterior angles of all polygons total 360 degrees.
Regular polygons are those polygons that are bothequilateral (all sides congruent) and equilateral (all interior angles congruent).
regular polygons
two polygons with sides that have all equal sides and angles
All regular polygons have equal lengths and equal interior angles but irregular polygons have variations in sizes.
There are lots of different types of polygons Polygons are classified into various types based on the number of sides and measures of the angles.: Regular Polygons Irregular Polygons Concave Polygons Convex Polygons Trigons Quadrilateral Polygons Pentagon Polygons Hexagon Polygons Equilateral Polygons Equiangular Polygons
