Question

If three parallel lines are cut by a transversal and one angle is measured to be 90 degrees, what can be said of the remaining?

a. there all 90 degrees
b. only some of the remaining angles are 90 degreesc. they will all be complementary to each other
d. there isn't enough information to determine anything about the remaining angles

Answer 1

I think the correct answer would be that they are all 90 degrees. The transversal line cuts the parallel lines into four segments perpendicularly so the angles should be 90 degrees. Hope this helps. Have a nice day. Feel free to ask more questions.
