A polygon has an equal number of sides and angles. For example, a triangle has 3 sides and 3 internal angles.
A 1000-sided shape is called a chiliagon. It is a polygon with 1000 sides and 1000 angles. The sum of the interior angles of a chiliagon is 179,640 degrees. It is a regular polygon, meaning all its sides are of equal length and all its angles are equal.
''Decagon'' is any polygon with ten sides and ten angles ''Regular decagon'' is a polygon with ten sides of equal length and all angles equal to 144°
Four sides
A polygon with 27 sides is called a heptacosagon. The name is derived from the Greek words "hepta" meaning seven and "cosi" meaning twenty. The heptacosagon has 27 vertices and 27 angles, with the sum of its interior angles equal to 4050 degrees.
A polygon with sides of equal length and equal angles is termed a regular polygon.
A polygon has 3 or more sides and is called regular when all sides and angles are equal and it is irregular when its sides and angles are not equal.
A polygon with 6 equal sides is called a regular hexagon (regular if it has all angles equal).
A polygon whose sides are not equal is known as an irregular polygon. A regular polygon has equal sides and angles.
All of the angles are equal in a "regular" polygon. (All of the sides are too.)
A regular polygon
It is called an irregular polygon. However, an irregular polygon can have congruent sides if all angles are not equal.
A regular polygon has equal angles AND sides.
There is no special name for that. However, if the sides are also equal, it is called a regular polygon.
It is then called a regular polygon when all angles and sides are of equal values.
Not only can a regular polygon have equal angles and sides, it must have them.
It is then classed as a regular polygon such as a square or an equilateral triangle.
