Question 951864: ΔABC has the vertices A(0, 0), B(-8.5, 3), and C(0, 6), and ΔAXY has the vertices A(0, 0), X(-3, -8.5), and Y(-6, 0). Which transformation can be used on ΔABC to show that ΔABC is congruent to ΔAXY?

The transformation rotated everything around the origin by 90%5Eo counterclockwise.
Every point stays the same distance from the origin, but in a different direction.
Point (a,0) turns into point (0,a);
point (0,b) turns into point (-b,0), and (adding them up)
point (a,b) turns into point (-b,a):
(0,0) ---> (-0,0) = (0,0)
(-8.5,3) ---> (-3,-8.5)
(0,6) ---> (-6,0)
