WEBReference Angle Definition. The reference angle is the smallest possible angle made by the terminal side of the given angle with the x-axis. It is always an acute angle (except when it is exactly 90 degrees). A reference angle is always positive irrespective of which side of the axis it is falling.

WEBThe reference angle is the positive acute angle that can represent an angle of any measure. The reference angle must be <90∘ must be < 90 ∘ . In radian measure, the reference angle must be < π 2 must be < π 2 . Basically, any angle on the x-y plane has a reference angle, which is always between 0 and 90 degrees.
