The figure shows three right triangles. Triangles UVW, UZV, and VZW are similar.

Theorem: If two triangles are similar, the corresponding sides are in proportion.

Figure shows triangle UVW with right angle at V. Segment UV is 2 and segment VW is 3. Point Z is on segment UW and angles VZU and VZW are right angles.

Using the given theorem, which two statements help to prove that if segment UW is x, then x2 = 13?
