The diagram shows ADEF and AXYZ.

Z
To prove ADEFAXYZ, Trisha starts by translating ADEF to get AD'E'F' where E' = Y. Then
she rotates AD'E'F' about point Y to get AD"E"F" with D" = X.
Which is a good next step for Trisha's proof?
Show that after the rotation F" = Z.
Rotate AD"E"F" about point X to get AD"E"F" so that D"E" and XZ coincide.
Reflect AD"E"F" across XY to get AD"E"F" and show that F"" = Z.
Reflect AD"E"F" across a vertical line to map AD"E"F" onto AXYZ.
