Question : I have a test tomorrow and I have sample questions.
These are what I have to find for 120degrees:
Instructions: Graph the following and find two (one +, one -) co-terminal angles.
the teacher told me the answer to 120 degrees was: 480 degrees and -240 degrees.
How do I solve these kinds of problems? please help
Answer : You add 360, or subtract 360 to an angle and you get a coterminal angle. So, in your example: 120 + 360 = 480, so 120 and 480 are coterminal. Also 120 - 360 = -240, so 120 and -240 are coterminal. Geometrically, adding 360 rotates the terminal angle around one complete revolution and it comes back and lands on top of where it was. The word CoTerminal comes from "Common Terminal" side, i.e. the terminal sides coincide. You can also add 2 complete revolutions, that would add 720 degrees, etc... More from Yahoo Answers
