Question

A student says that the measures of coterminal angles are never opposites of each other. Is the student correct?

Answer 1

The student is wrong. Two angles are coterminal if and only if the difference between their measures is a multiple of 360°.

The difference between the angles 180° and –180° is 360°, and they are coterminal. Therefore the student is WRONG.
