This may seem odd, as in daily life we think of a square as not being a rectangle ... but in mathematics it is. A quadrilateral is a polygon in Euclidean plane geometry with four edges (sides) and four vertices (corners). All rhombuses are parallelograms, but not all parallelograms are rhombuses. 360. sum of the exterior angles of any polygon. Kite has two pairs of equal adjacent sides and one pair of opposite angles equal. See below for more details. This makes the square the only equilateral and equiangular quadrilateral. In the rhombus, angle 1 = 10x, angle 2 = x + y, and angle 3 = 15z. Of course, we can just call it a "regular quadrilateral."
