where k is any negative or positive integer. Related Topics: More Lessons on Trigonometry An angle is said to be in standard position if it is drawn on the Cartesian plane (x-y plane) on the positive x-axis and turning counter-clockwise (anti-clockwise). Finding coterminal angles is as simple as adding or subtracting 360 ° or 2π to each angle, depending on whether the given angle is in degrees or radians .
Coterminal angles A c to angle A may be obtained by adding or subtracting k*360 degrees or k* (2 π). Coterminal angles are two angles that are drawn in the standard position (so their initial sides are on the positive x-axis) and have the same terminal side like 110° and -250° Another way to describe coterminal angles is that they are two angles in the standard position and one angle is a multiple of 360 degrees larger or smaller than the other.

Coterminal Angles Angles that have the same terminating side are coterminal. Coterminal Angles Coterminal angles are angles in standard position (angles with the initial side on the positive x -axis) that have a common terminal side.For example 30 ° , − 330 ° and 390 ° are all coterminal. or A c = A + k*(2 π) if A is given in radians. The initial side of an angle is the ray where the measurement of an angle starts.
