The measure of the exterior angle of a triangle must be greater than the measure of either non-adjacent interior angle.
This is because the measures of the exterior angle and its adjacent interior angle must add up to 180 since they are a linear pair. But the measures of the two non-adjacent interior angles must also add with the adjacent one to get 180 since the measures of the 3 angles of a triangle add up to 180.
So the exterior angle's measure equals the sum of the two non-adjacent interior angles, and therefore must be bigger than either one of them.
Good luck, hope that helps.

In a triangle, an exterior angle is supplementary to the adjacent interior angle and is greater than either of the non-adjacent interior angles.

Well this isn't the best place to ask a question like that I know how to do it but you can't explain it on here
okay well just put "exterior angle ineaqality" into google and it should show you great examples, or go to your text book's website usually math books have examples on there webpages, or ask a friend or teacher, someone that really gets it. good luck!
If you found this helpful please press "best answer." Thanks!
