Practice graphing angles in standard form, finding a positive and negative coterminal 80^{\circ} + 360^{\circ}\times 2 &= 80^{\circ} + 720^{\circ} \\\\ Positive Coterminal Angles of -25 = 335, 695, 1055, 1415. WebPositive and negative coterminal angles In the example above, we find that 405 and -315 are the coterminal ` User reviews. Then, multiply the divisor by the obtained number (called the quotient): 3601=360360\degree \times 1 = 360\degree3601=360. Find Positive And Negative Coterminal Angles Example. For the most negative coterminal, find the first coterminal less than 0. For example, notice that 45 degrees and -315 degrees are coterminal angles because they both start and stop at the same place, but just differ in their amount or direction of rotation. Once youve determined the coterminal angles, you can convert them to radians. Then, in the beginning, our angle is {eq}0^{\circ} {/eq}. An angle of 140 and an angle of 220 are coterminal angles. For example, 100 and 460 are coterminal for this reason, as is 260. But what if we are asked to find a coterminal angle less than 360 but greater than zero?
