The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle. Under this definition, two angles are congruent provided either can be made to coincide (the vertex and the sides) with the other by a rigid motion.
In geometry and trigonometry, a right angle is an angle of exactly 90Â° (degrees),[1] corresponding to a quarter turn.[2] If a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles.[3] The term is a calque of Latin angulus rectus; here rectus means upright, referring to the vertical ...
