Question 745268: RST is similar to UVW which proportion is NOT true?

a) RS/UV= ST/VW
b) RT/VW= RS/UW
c) UV/RS = UW/RT
d) VW/ST = VU/SR

Similar triangles are listed with corresponding vertices and sides in the same order, so the pairs of corresponding sides are
1) RS and UV
2) ST and VW
3) RT and UW
Note that the sides can be named either way. RS can be called SR and UV can be called VU. In fact that happens in answer choice d).
The proportions that are true involve ratios of the same set of 2 pairs.
For example the ratios of (RST side)/(UVW side) are the same for sides from pair 1 (RS/UV) and sides from pair 2 (ST/VW).

a) involves side pairs 1 and 2
b) involves sides from pairs 1, 2, and 3, so it has to be wrong
c) involves side pairs 1 and 3
d) involves side pairs 1 and 2

b) is not true
