Which of the following best completes the proof showing that ΔWXZ ~ ΔXYZ?

triangles WXZ and XYZ that share side XZ with right angle XZW, WZ equals 16, XZ equals 12, and YZ equals 9

Since segment XZ is perpendicular to segment WY, angles WZX and XZY are both right angles and congruent. The proportion _ shows the corresponding sides are proportional, so the triangles are similar by the SAS Similarity Postulate.
