Answer:

B. RY/RS=RX/RT=XY/TS

Step-by-step explanation:

In the picture attached, △RST and △RYX (which are similar) are shown

The options are:

  • A. RY/YS=RX/XT=XY/TS
  • B.RY/RS=RX/RT=XY/TS
  • C.RY/RS=RX/RT=RS/RY
  • D.RY/RX=RS/RT=XY/TS

Given that the triangles are similar, then their sides are proportional. Then, there is some constant k, which satisfies:

k*RS = RY

k*RT = RX

k*TS = XY

This can be rewritten as:

k = RY/RS = RX/RT = XY/TS

Since △RST and △RYX are similar triangles, the statement that must be true is:

B. RY/RS = RX/RT = XY/TS

Sides of Similar Triangles

  • If two triangles are similar to each other, then, the ratio of their corresponding side lengths must be equal to each other.

Thus, △RST and △RYX  are similar triangles.

  • Therefore:

RY/RS = RX/RT = XY/TS

Therefore, since △RST and △RYX are similar triangles, the statement that must be true is:

B. RY/RS = RX/RT = XY/TS
