## Mathematical background

In the situation of triangles, gift equiangular requires that the triangle likewise be equilateral. The is, every equiangular triangle is a continual triangle. However, this is no the case for every polygons. Because that example, a rectangle is equiangular — all four angles space 90° — yet need not be square (need not have actually all 4 sides the exact same length). Thus, no all equiangular quadrilaterals space equilateral and so room not every regular.
