Which represents the measures of all angles coterminal with a 400° angle?
A student says that the measures of coterminal angles are never opposites of each other. Is the student correct? Explain.
The student is incorrect. For two angles to be coterminal, the difference between their measures must be a multiple of 360°. If we consider the measures 180° and -180°, these two values are opposites of each other. The difference between them is 180° - (-180°) = 360°, which is a multiple of 360°. Therefore, 180° and -180° are coterminal angles that are opposites, proving the student's statement is false.
Select all that are measures of angles coterminal with a 145° angle.
