The triangles ΔRST and ΔXYZ are congruent. Points P and W lie on ST and YZ, respectively. Which of the following statements are true?
A) If P is the midpoint of ST and W is the midpoint of YZ then ΔRSP≅ΔXYW.
B) If RP bisects ∠SRT and XW bisects ∠YXZ, then ΔRSP≅ΔXYW.
C) If RP=ST and XW=YZ, then ΔRSP≅ΔXYW.
D) If RP is perpendicular to ST and XW is perpendicular to YZ, then ΔRSP≅ΔXYW.
Type your answer as a list of letters separated by commas. For instance, if you believe that conditions A, B, and C are enough, then type "A,B,C" into the answer box. If you believe none of the options are correct, enter "none."
