The rhombus has adjacent angles being the same, and all sides are equal. However, it is not necessarily equiangular.
A rectangle comes to mind. A rectangle is equiangular (all angles the same) and is also a quadrilateral (four-sided), but is not equilateral (all sides of the same length).
A rhombus is always equilateral. It need not be equiangular, but if it is, then most people look at it and call it a "square".
Yes, all the angles of an equilateral triangle are always 60 degrees.
A regular polygon must be equiangular as well as equilateral. A rhombus is an example of a polygon that is equilateral but not equiangular.
Yes, because to be classified as a square it must be equiangular and equilateral and be a quadrilateral.
A rectangle is not always equilateral, although it is always equiangular. A rhombus is not always equiangular, but is always equilateral. A square is both equilateral and equiangular.
A rhombus if i remember my geometry its a rhombus A rhombus is NOT equiangular. A square is the only quadrilateral with equal sides and equal angles. An equilateral triangle is also equiangular. Polygons that are equilateral and equiangular are called regular.
A square has four sides so it is a quadrilateral. All sides of a square are of equal length so it is equilateral. All angles of a square are of equal measure so it is equiangular. A quadrilateral that is equilateral and equiangular is a regular quadrilateral.
Yes! It's called a rhombus.
Yes, by definition. If it not equilateral AND equiangular, then it is not regular.
A square is an equilateral rectangle or an equiangular rhombus or a regular quadrilateral.
