How can abc be mapped xyz? first pull down is either vertex x, vertex y, or vertex z?

Hiya!

First, translate vertex A to vertex X. Next, rotate angle ABC to align the sides and angles.

How I got this? Simple! Notice how both shapes are the exact same, down to the exact measurements. Now, imagine a four-quadrant grid with (0, 0) is between point C and Y. ABC is in the top left quadrant and XYZ is in the lower right. If you rotated the whole thing, they'd overlap. Vertex A is actually vertex X, theoretically.
