The triangles triangle RST and triangle XYZ 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 line ST and W is the midpoint of line YZ then triangle RSP≅ XYW
(b) If RP bisects angle RST and line XW angle YXZ, then RSP ≅ XYW
(c) If RP = ST and XW = YZ, then triangle RSP ≅ XYW
(d) If RP ⊥ ST and XW ⊥ YZ, then triangle RSP ≅ XYW
This is multiple choice problem and if none of the answers work type none.
