Determine wether triangle deef is cogruent to triangle pqr given the coordinates of the verticles. D(-6,1),E(-1,-4),P(0,5),Q(7,6),R(5,0)

The length of DE equals the length of PR, which means that congruence is not impossible.

However, the coordinates of F is missing, so it is not possible to determine if DEF is congruent to PQR.

Well, by a simple vector calculation in the plane, you can easily find the last verticle. However, I interpret the question just as MathMate did.
