I have a question about geometry. How do you solve Given that r||s and q is a transversal, we know that by the [________]?

Question

Answer 1

All I can tell you is that angles 2,3,6,7 are=.

1,4,5,8 " "

angles 1&2, 2&4, 4&3, 3&1 are supplementray.

Same for line "s".

Q is transversal because of the 2 lines intersecting.

Answer 2

When 2 parallel lines are cut by a transversal, the corresponding angles are equal and the alternate-interior angles are equal. For example, angle 4 and angle 8 are equal and angle 4 and angle 5 are equal.
