Which is a possible set or rigid motions make the statement true? A. f(x, y) = (x + 4, y - 6)

B. f(x, y) = (2x, 2y)

C. f(x, y) = (2x + 4, 2y)

D. f(x, y) = (x/2, y/2)

I need an answer ASAP

Given: abcd is a square. prove: ac ? bd. we are given that abcd is a square. if we consider triangle aeb and triangle aed, we see that side is congruent to side ad because sides of a square are congruent. we know that side ae is congruent to side ae by using the . finally, we know that side de is congruent to side because the diagonals of a square bisect each other. therefore, triangle aeb is congruent to triangle aed by congruency. we see that angle aed and angle aeb are a linear pair, and congruent by cpctc. thus, the measure of these angles will be 90°, and diagonal ac is perpendicular to diagonal bd by the .
