Given: trianglestu with line segment s t is parallel to line segment x y

prove: startfraction s x over x u endfraction = startfraction t y over y u endfraction

triangle s t u is cut by line segment x y. line segment x y goes from side u s to side u t. angle u y x is 1, angle y x u is 3, angle u t s is 2, and angle t s u is 4.

complete the steps of the proof.
