Just need to pass this geometry to be done
what are possible coordinates of point f if δdef is congruent to δabc?

(–1,4)
(4,–1)
(0,–1)
(–1,0)

(–1,4)

Shapes are congruent if you can turn one into the other by moving, rotating or flipping. We can use this symbol to show that two things are congruent. Two triangles are congruent if and only if all the corresponding legs are congruent. The only point that makes the corresponding legs to be congruent is . Why? because we can match these two triangles by flipping the red one two times and moving it into the blue one.

the answer is d. (1.2, -4.7) on edgn

hope this !
