Answer:
Angle 3 is = to angle 2 because:
Angle 3 & angle 7 are corresponding angles, meaning they have the same measure.
Angle 7 & angle 2 are vertical angles, meaning they also have the same measure.
Therefore, if angle 7 is equal to angle 3, then angle 2 must also be equal to angle 3.
Hope this helps! Have a great day!
