How to Find Coterminal Angles in 3 Easy Steps - WikiHow The maximum amount of times 360 degrees can be subtracted from 785 degrees and stay positive is found by dividing the given angle, 785 degrees and dividing it by 360 but rounding down to the closet whole number. Adding one revolution would be considered the smallest positive coterminal angle. Every angle greater than 360 or less than 0 is coterminal with an angle between 0 and 360, and it is often more convenient to find the coterminal angle within the range of 0 to 360 than to work with an angle that is outside that range.

The greatest negative coterminal angle is (Simplify your answer. The procedure to use the coterminal angle calculator is as follows: Step 1: Enter the angle in the input field, Step 2: Now click the button Calculate Coterminal Angle to get the output, Step 3: Finally, the positive and negative coterminal angles will be displayed in the output field. Answers may vary. Since 90 90 is in the first quadrant, the reference angle is 90 90 . Solution for Find the least positive and the greatest negative coterminal angles of the following angle measures. Save my name, email, and website in this browser for the next time I comment. An angle with measure 800 is coterminal with an angle with measure 800 360 = 440, but 440 is still greater than 360, so we subtract 360 again to find another coterminal angle: 440 360 = 80. Step 3: Click on the "Calculate" button to find the coterminal angles. 45+360=405 We can say that 45 and 405 are coterminal.
