For 1st fig:
Angles whose measure is greater than angle 8 is:
<4,<5,<9
For 2nd fig:
Angles whose measure is less than angle 4 is:
<2,<5,<7
▶Explanation:
❇Statement of Exterior angle inequality theorem:
↪An exterior angle of a triangle is greater than either of the non-adjacent interior angles.
➡So for 1st fig ,< 4,<5,<9 were exterior angles of triangle which would obviously be greater angle than interior angle 8 by the theorem.
➡Similarly, for 2nd fig, <2,<5,<7 were non adjacent interior angles which would obviously be less in measure than exterior angle 4.In this case , see both triangles to not get confused.
