Question

Select which pair of lines can be proven parallel by using the given angle measures.

A. L || n
B. a || c
C. b || c
D. a || b

Answer 1

c) b // c

Explanation:

Two lines are said to be parallel when one of the conditions is true.

1) Corresponding angles are equal.

2) Alternate interior angles are equal.

3) Co interior angles are supplementary.

∠1 =115° {Vertically opposite angles}

∠1 = ∠2 = 115°

If corresponding angles are equal, then the lines are parallel. So, b // c
