Triangle xyz is similar to triangle xvw. write the congruence statements that must be true.
Lunna [17]

Answer:

∠ Y = ∠ V

∠ Z = ∠ W

\frac{XY}{XV} =\frac{YZ}{VW} =\frac{XZ}{XW}

Step-by-step explanation:

It is given that Δ XYZ is similar to Δ XVW.

Since corresponding angles of similar triangles are equal,

∠ X = ∠ X

∠ Y = ∠ V

∠ Z = ∠ W

Also, since corresponding sides of similar triangles are in proportionate,

\frac{XY}{XV} =\frac{YZ}{VW} =\frac{XZ}{XW}
