An equilateral triangle and a square.
Equilateral and Equiangular triangle
All regular polygons.
An equilangular polygon is a polygon who's angles are equal.
A polygon cannot be equilateral but not equiangular because in the definiton of a regular polygon which is a polygon that is both equiangular and equilateral you see that you cannot have one without the other. As long as a polygon is equilateral it is also equilangular and vice versa. ARBETTES: You cannot have both in all polygons. In all triangles this is true. If a triangle is equilateral then it is equiangular. However, let's take a known quadrilateral: Rhombus. The definition of a Rhombus is that it has all equal sides. That's it. It's oppsite angles have to be congruent, but they do not all have to be 90 degrees.
An irregular polygon need not be equiangular.
a regular polygon is always equilateral
Yes, a square is an equilateral polygon
A regular polygon must be equiangular as well as equilateral. A rhombus is an example of a polygon that is equilateral but not equiangular.
equilateral triangle is an example of regular polygon
An equilateral polygon is one in which all sides are equal
