Answer:
Explanation:
Two angles form linear pair if they are adjacent angles and their non common arms are opposite rays.
Corresponding angles: When two parallel lines are intersected by the transversal, the angles formed on the matching corners of the same side of the transversal are called corresponding angles.
∠1 + ∠2 = 180° {Linear pair}
135 + ∠2 = 180
∠2 = 180 - 135
∠2 = 45°
∠6 = ∠2 {Corresponding angles}
∠6 = 45°
