Question

PLEASE HELP!!!! Write a paragraph to prove that the measure of angle 1 is equal to the measure of angle 3.

Answer 1

Use the fact that angles on a straight line add to 180 degrees.

Answer 2

alternatively you could say angle 2 is 180 - angle 1 but also 180 - angle 3 (since angle 2 lies on both lines)
So angle 1 = angle 3.

Answer 3

You deserve it!
You are a hard-working helper!
