Given the two squares above, determine how triangles STV and YZX can be shown to be similar.
A.
Since VST YZX and STV XYZ, the triangles are similar by angle-angle.

B.
Since VST XYZ and STV YZX, the triangles are similar by angle-angle.

C.
Since VST XYZ and VS = ST, the triangles are similar by angle-side.

D.
Since STV YZX and VS = ZY, the triangles are similar by angle-side.
