Question

Given: Angle 2 and Angle 4 are vertical angles
m angle 2 = 125 degrees

Prove: m angle 4 = 125 degrees

Answer 1

(I'm not too sure on how to do this type of thing)
Given: Angle 2 and Angle 4 are vertical angles
m∠2 = 125°

Prove: m∠4 = 125°

Answer 2

you should know that vertical angles are congruent.

Each angle and its adjacent angle form a straight angle. So, the adjacent angles are 55°.

125+55 = 180
55+125 = 180
