Right Angle
A right angle adalah satuan dari angular measure sama dengan exactly 90°, or one quarter of a full turn. It didefinisikan sebagai 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.
