Example Question #7 : Angles
Which of the following angles is coterminal with ?
For an angle to be coterminal with , that angle must be of the form for some integer - or, equivalently, the difference of the angle measures multiplied by must be an integer. We apply this test to all five choices.

is the correct choice, since only that choice passes our test.
Example Question #1 : Understanding Coterminal Angles
Find a coterminal angle for .
Coterminal angles are angles that, when drawn in the standard position, share a terminal side. You can find these angles by adding or subtracting 360 to the given angle. Thus, the only angle measurement that works from the answers given is .
Example Question #22 : Graphing The Sine And Cosine Functions
Which of the following angles is coterminal with ?
Each angle given in the other choices is coterminal with .
Each angle given in the other choices is coterminal with .
For an angle to be coterminal with , that angle must be of the form for some integer - or, equivalently, the difference of the angle measures multiplied by must be an integer. We apply this test to all four choices.

All four choices pass the test, so all four angles are coterminal with .
Example Question #3 : Understanding Coterminal Angles
.
Example Question #2 : Understanding Coterminal Angles
Which of the following choices represents a pair of coterminal angles?
For two angles to be coterminal, they must differ by for some integer - or, equivalently, the difference of the angle measures multiplied by must be an integer. We apply this test to all five choices.
