When two lines are parallel and a transversal crosses them, several angles are formed that have specific relationships.
If angle 1 measures 135°, and it is formed with angle 2 by a transversal that intersects the parallel lines M and N, then angle 2 can be determined based on the type of angle relationships.
Considering that angle 1 and angle 2 are corresponding angles, they are equal when the lines are parallel. Therefore, if angle 1 = 135°, then angle 2 must also be:
Angle 2 = 135°.
