how can you tell when an exterior angle is equal to another exterior angle without making the mistake of looking at an interior angle?
so basically the differences, how to spot

well, the way i would solve your problem, would be by actually looking at the sizes of the interior angles, if they match, then the exteriors should be equal too.
yup thats rightif the interior angles are equal the the exterior angles are equal since int angle + ext angle = 180 degrees
