square
An equilateral and equiangular polygon.
a square. or an equilateral triangle
Equiangular just means that all of the angles are the same, but the term is most often used to describe an equilateral triangle.
Not all are. Not only is it a concave shape, but the interior angles can vary. For a polygon to be regular, it must be equilateral and equiangular.
It is an equiangular triangle it is correct.
Equiangular quadrilaterals are four-sided polygons that have equal angles. These include squares (90 degree angles) and rectangles (90 degree angles).
It is called a square. The clues: equilateral means all sides are of equal length; equiangular means all angles are of the same degrees; quadrilateral means the shape has four sides. The only shape that qualifies is a rectangle [includes squares.]
A shape where all the sides are equal and all the angles are equal. If all sides are equal but angles or not, it is equilateral. If it is vice versa, it is equiangular.
Having equal angles; as, an equiangular figure; a square is equiangular.
