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 10, XZ equals 5, and YZ equals 2 and one half

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.

5 over 10 equals 5 over 2 and one half

5 over 10 equals 5 over 5

10 over 5 equals 5 over 2 and one half

10 over 5 equals 2 and one half over 5
