There are many such shapes and there is no specific name.
Any 8 sided polygon is called an octagon. If all of the sides and angles are equal, then it's called a regular octagon.
A four-sided polygon with four congruent sides and four equal angles is a square
A regular polygon has equal lengths of each side, AND the same angle between each of the sides. A Square is a polygon, an equilateral triangle is a polygon, a pentagon is a five - sided polygon, and so on.
It is impossible to have a two-sided regular polygon with equal length sides. The two sides would merely form an open angle, with no closed third side.
A ten sided polygon is called a Decagon.
A regular polygon has equal length sides while a polygon does not have to have equal sides.
A 3 sided polygon with 2 equal sides is an isosceles triangle
Any 8 sided polygon is called an octagon. If all of the sides and angles are equal, then it's called a regular octagon.
A four-sided polygon with four congruent sides and four equal angles is a square
Equilateral triangle.
A regular polygon has equal lengths of each side, AND the same angle between each of the sides. A Square is a polygon, an equilateral triangle is a polygon, a pentagon is a five - sided polygon, and so on.
A 3 sided polygon with 2 equal sides is an isosceles triangle
A polygon with 10 sides is called...
It is impossible to have a two-sided regular polygon with equal length sides. The two sides would merely form an open angle, with no closed third side.
trapezoid
It can be if all the sides are of equal length.
A four-sided polygon with all sides parallel and congruent is a rhombus. If all the angles are equal, it is a special case of a rhombus called a square.
