What is the conversion formula from radians to degrees?

Back

Degrees = Radians × (180/π)

Front

What is a coterminal angle?

Back

Coterminal angles are angles that share the same terminal side when drawn in standard position. They can be found by adding or subtracting multiples of 360 degrees or 2π radians.

Front

What is the standard position of an angle?

Back

An angle is in standard position when its vertex is at the origin of a coordinate system and its initial side lies along the positive x-axis.
