Question

BRAINLIEST ASAP! PLEASE HELP ME :)

Answer 1

Agreed with the other answer. Angles 1 and 2 are on the exterior of the lines u and v. Refer to the diagram below. The red region is the interior while the blue regions collectively define the exterior.

Also, the green line is the transversal. Angles 1 and 2 are on alternating sides of the transversal.

Put together, we simply refer to angles 1 and 2 as alternate exterior angles. If we know they are congruent, then we can use the converse of the alternate exterior angle theorem to prove lines u and v are parallel.

Answer 2

The answer is the Alternate Exterior angles theorem. This is due to the fact that the angles are both outside and they are on alternate sides of the line. Hope this helps!
