Given these two angles:


(5\pi)/(4)
-(3\pi)/(4)

You need to remember that, by definition, two angles are coterminal if the Difference (the result obtained by subtracting them) is:


360\text{\degree or }2\pi

Then, you need to set up:


(5\pi)/(4)-(-(3\pi)/(4))

Solving the Subtraction, you get:


=(5\pi)/(4)+(3\pi)/(4)
=(8\pi)/(4)
=2\pi

Hence, the answer is: They are Coterminal Angles.
