What must be true for lines a and b to be parallel lines? Select four options. m1 = m2 = 58 x = 20 = 1 = 58 = 58 x = 19 + + m2 = 180

Step-by-step explanation:

It's important to know that parallel lines have equal slopes, becasue the condition of parallelism is , for line 1 and line 1.

In the image attached you can observe all the given choices. The second image attached shows all lines involved.

Notice that lines a and b are vertical. To be parallels , because those angles are corresponding angles. Also, , because those angles are alternate exterior angles.

Using supplementary angles theorem, we have

Therefore, based on the analysis above, the right asnwers are a, b, g and h.

you answer is a
