Frank shows that triangle A is congruent to triangle B by rotating triangle A around point J and then translating it so it matches up with triangle B exactly. Which conclusion can be drawn from Frank's transformations?

Which statement explains how you could use coordinate geometry to prove the opposite sides of a quadrilateral are congruent? a. use the slope formula to prove the slopes of the opposite sides are the same. b. use the slope formula to prove the slopes of the opposite sides are opposite reciprocals. c. use the distance formula to prove the lengths of the opposite sides are the same. d. use the distance formula to prove the midpoints of the opposite sides are the same.
