Letters a, b, c, and d are angles measures. which equation is enough information to prove that lines m and n are parallel lines cut by transversal p? check all that apply. a = c a = d c = d b + c = 180° b + d = 180°

The answers are:

a = c

c = d

b + d =180 degrees

Here's how:

When a line intersects two parallel lines, then corresponding angles are formed which means the same corners are congruent.

option c = d is considered.

And, because of vertical angles,

a = d is also an answer.
