Answer:
Angles 3, 4, and 6
Step-by-step explanation:
Theorem:
The measure of an exterior angle of a triangle equals the sum of the measures of the remote interior angles.
Angle 8 is an exterior angle, and angles 4 and 6 are its remote interior angles. According to the theorem, the sum of the measures of angles 4 and 6 equals the measure of angle 8, so the measures of angles 4 and 6 must be less that he measure of angle 8. Since angles 3 and 4 are vertical angles, they are congruent, so the measure of angle 3 must also be less than the measure of angle 8.
Answer: Angles 3, 4, and 6
