Is there a series of rigid transformations that could map triangle RST to triangle XYT ? If so, which transformations could be used?

A
No, triangle RST and triangle XYT are not congruent.
B
Yes, triangle RST can be reflected across the line containing line segment RT and then rotated about cap t so that cap s is mapped to cap y .
C
Yes, triangle RST can be translated so that cap s is mapped to cap y and then rotated about cap s so that cap r is mapped to cap x .
D
No, triangle RST and triangle XYT are congruent but triangle RST cannot be mapped to triangle XYT using a series rigid transformations.
