Triangle Rectangle - Diagram - Angle Transparent PNG is a 1444x730 PNG image with a transparent background. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal (360°/4 = 90°); or a parallelogram containing a right angle. Each diagonal divides the square into two congruent isosceles right-angled triangles.
