Question
Which two of the following are not coterminal with $r^{\circ} ?$A. $360^{\circ}+r^{\circ}$B. $r^{\circ}-360^{\circ}$C. $360^{\circ}-r^{\circ}$D. $r^{\circ}+180^{\circ}$
Step 1
Coterminal angles are angles in standard position (angles with the initial side on the positive x-axis) that have a common terminal side. In other words, two angles in standard position are coterminal if and only if they have the same terminal side. Show more…
