Someone, please help me!! The two triangles can be shown to be similar by performing transformations. First, ∆ABC is rotated 180° around point A. Then ∆A'B'C' is dilated by a factor of k units with a center of dilation at point A. Finally, ∆A''B''C'' is translated p units to the right and q units down to map onto ∆CDE.

What are the values of k, p, and q?
