Question

Which of the following are exterior angles check all that apply?

Answer 1

The exterior angles on this diagram are angle 4 and angle 2.

We can see this because an exterior angle is the angle that forms a straight line with an interior angle, so that 180 - [interior angle] = [exterior angle].

Therefore, angles 4 and 2 are the only angles that form straight lines with interior angles, so they are thus the exterior angles.

I hope this helps!
