Answer:
Segment RW congruent to segment XY
Explanation:
SAS means side-angle-side.
You are given two congruent angles, so you already have the angle you need for SAS.
By the reflexive property, side XW is congruent to itself, so now you have a side also.
You need another pair of sides, but the two sides must include the angle.
