Ethan is proving that the slope between any two points on a straight line is the same. He has already proved that triangles 1 and 2 are similar.

Drag statements and reasons to complete the proof.

On a coordinate plane, a line goes through points P, Q, and R. Triangle 2 has sides P Q, E, and F. Triangle 1 has sides Q R, E prime, and F prime.
