Convert right angle to degrees
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.
Degree
A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle, defined so that a full rotation is 360 degrees.
It is not an SI unit, as the SI unit of angular measure is the radian, but it is mentioned in the SI brochure as an accepted unit.[4] Because a full rotation equals 2π radians, one degree is equivalent to π/180 radians.
