Right angle conversion
In geometry and trigonometry, a right angle is an angle that bisects the angle formed by two halves of a straight line. More precisely, if a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles.
Radian is the standard unit of angular measure that defines the ratio between the length of arc and its radius. Radian is a former SI supplementary unit, but since 1995 when this category was abolished it is considered a SI derived unit.
