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

A
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 .
B
No, triangle RST and triangle XYT are congruent but triangle RST cannot be mapped to triangle XYT using a series rigid transformations.

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 .
D
No, triangle RST and triangle XYT are not congruent.

Which best explains if quadrilateral WXYZ can be a parallelogram?

A
WXYZ cannot be a parallelogram because the value of x that makes one pair of sides congruent does not make the other pair of sides congruent.
B

C
WXYZ can be a parallelogram with one pair of sides measuring 15 mm and the other pair measuring 9 mm.
D
WXYZ cannot be a parallelogram because there are three different values for x when each expression is set equal to 15 .
