A negative coterminal angle A c may be given by. 1 Angles formed by two rays are also known as plane angles as they lie in the plane that contains the rays. Add 360 360 to 270 - 270 . 3 3. One angle (DBC) has a measure of 72, and the other (ABC) has a measure of 432, but they are coterminal because their terminal sides are in the same position. A c -200 - 360 -560. 320 320 . (example 745) in Radians second input. Find an angle that is positive, less than 360&176; 360 &176;, and coterminal with 75&176; - 75 &176;. a) 10&176;, 370&176;. Greek letters are often used as variables for the measure of an angle. Step 1 To find a positive angle, add 360 560 360 920. Use the below online coterminal angle calculator to find out the positive and negative coterminal angles. Prove isosceles triangle. Coterminal Angles. 3) State what a positive or negative angle signifies, and explain how to draw each. Find two positive angles and two negative angles that are coterminal with the given angle. 1000 1000. Formula How to Find Coterminal Angles. It serves as a reference point to determine the exact values of trigonometric functions, such as sine, cosine, and tangent. 135&176; 135 &176;. Step 1 Given angle , find a coterminal angle having measure between 0&176; and 360&176;. Subtract 150. Greek letters are often used as variables for the measure of an angle. In this position, the vertex (B) of the angle is on the origin, with a fixed side lying at 3 o'clock along the positive x axis. 320&176; 320 &176;. We can find coterminal angles by adding or subtracting 360 or &92;(2&92;). Any angle has infinitely many coterminal angles because each time we add 360&176; to that angleor subtract 360&176; from itthe resulting value has a terminal side in the same location.
