Final answer:
The proportion that shows the corresponding sides are proportional is 5 over 10 equals 5 over 2 and one half.
Step-by-step explanation:
The proportion that shows the corresponding sides are proportional is 1) 5 over 10 equals 5 over 2 and one half.
In the given scenario, segment XZ is perpendicular to segment WY. This means that angles WZX and XZY are right angles and congruent. If the corresponding sides of two triangles are proportional, then the triangles are similar by the SAS similarity postulate. Therefore, the proportion 5 over 10 equals 5 over 2 and one half shows the corresponding sides are proportional, indicating that the triangles are similar.
