Answer:
Angle 2 is congruent to angle 4.
Step-by-step explanation:
A straight line equals 180 degrees. If the angle is not a right angle (90 degrees), two angles next to each other on the same line can not be equal. That is why angle 3 is not the answer.
Angle 3 = Angle 1 ; Angle 2 = Angle 4
Angle 1 + Angle 2 + Angle 3 + Angle 4 = 360 degrees
