Answer:
Angle 7 and angle 15
Step-by-step explanation:
- Alternate Interior Angles are a pair of angles on the inner side of each of those two lines but on opposite sides of the transversal.
Alternate interior angles with angle 9 are:
Transversal s, parallel lines are t and u,
- Angle 9 is in pair with angle 7
Transversal u, parallel lines are s and r,
- Angle 9 is in pair with angle 15
