Right Angle

A right angle is a unit of angular measure equal to exactly 90°, or one quarter of a full turn. It is defined as the angle formed when two straight lines meet perpendicularly, and is one of the most fundamental concepts in Euclidean geometry. Four right angles make up a complete revolution, and the right angle serves as the basis for defining complementary (90° − θ) and supplementary (180° − θ) angles.
