Question

Letters a, b, c, and d are angles measures. Lines m and n are cut by transversal p. At the intersection of lines p and m, labeled clockwise, from uppercase left, the angles are: a, b, c, blank. At the intersection of lines p and n, labeled clockwise, from uppercase left, the angles are: blank, blank, d, blank. Which equation is enough information to prove that lines m and n are parallel lines cut by transversal p? Select three options. a = c a = d c = d b + c = 180° b + d = 180°

Answer 2

Answer:

i. a = c

ii. c = d

iii. b + d = 180°

Step-by-step explanation:

A transversal is a line that intersects a line or two parallel lines, forming a series of  congruent angles.

In the description given, the following could be referred:

a = c (vertically opposite angle property)

c = d (vertically opposite angle property)

c + b = $180^{0}$ (sum of angles on a straight line)

b + d = $180^{0}$ (sum of angles on a straight line)

But the required equation for the prove are: a = c, c = d and b + d = $180^{0}$.
