A regular polygon.
If its acute angles are different then it is not a regular polygon but if it has 3 equal acute angles of 60 degrees then it is a regular equilateral triangle
A rhombus has four sides of equal lengths. So it is an equilateral polygon. But it is not an equiangular. It's angles are not equal in measure.
An equilateral polygon. All regular polygons, being equilateral, will have equal sides but it is not necessary that they are regular. A rhombus, for example, is equilateral but not regular.
A polygon is regular when all its sides are the same length and its internal angles are the same. It is said to be equilateral and equiangular, and that is what a polygon is when it is regular.
a regular polygon is always equilateral
A regular polygon is any polygon that has sides which are the same length and angles whose measures are equal. An equilateral triangle (also equiangular triangle) is a regular polygon. Other isosceles triangles (equilateral triangles are isosceles, but they are an exception) and scalene triangles are not regular polygons. A side note: Only in a triangle is a polygon regular solely if it is equilateral. (Since an equilateral triangle is equiangular as well). This is NOT always true in other polygons, like quadrilaterals, where it can be equilateral but not necessarily equiangular (a rhombus) or equiangular but not equilateral (a rectangle).
Octagon * * * * * An equilateral octagon (though not necessarily regular).
Regular polygon is equilateral and equiangular. Irregular polygon is non-equilateral and non-equiangular.
