Question

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? Select three options. a = c a = d c = d b + c = 180° b + d = 180°

Answer 1

Answer:

b + d = 180°, a = d and a = c

Step-by-step explanation:

With the figure we can see that the only way for them to be parallel is that the angles are similar with their counterpart, for example that a = d. a = c will show that all angles are equal in order to be m and n parallel. Finally b + d = 180° shows that the only way for this to be true is that m and n are parallel.
