Find the ratio of a side length in △XYZ to its corresponding side length in △RST.
Simplify your answer and write it as a proper fraction, improper fraction, or whole number.

Answer 1

Correspondence from △XYZ ~ △RST is X↔R, Y↔S, Z↔T. Matching given side pairs:
- XZ ↔ RT: 10/2 = 5
- ZY ↔ TS: 5/1 = 5
- YX ↔ SR: 10/2 = 5

Thus the ratio (△XYZ side)/(corresponding △RST side) = 5.
