given that lines a and b are parallel, what angles formed on line b when cut by the transversal are congruent with ∠2?
a) ∠5 and ∠6
b) ∠5 and ∠7
c) ∠6 and ∠7
d) ∠6 and ∠8

C)

Step-by-step explanation:

We know that when a transversal line passes through two parallel lines, then the corresponding angles and alternate ( both interior and exterior ) angles are congruent.

From the given figure, lines a and b are parallel.

 [∵ Vertical angles are congruent]

Also,  [∵ if a transversal passes through parallel lines then corresponding angles are congruent]

Also, [∵ if a transversal passes through parallel lines then alternate exterior angles are congruent]

Hence, the angles formed on line b when cut by the transversal are congruent with ∠2 are :-
