HELPPP!!!Kelsey uses the similarity statement to describe the triangles below.
Ganezh [65]

RT = 8 , RS = 3 AND ST = 5.4


RV = 4 , RU = 1.5 AND UV = 2.7


∴ RT/RV = 8/4 = 2


AND RS/RU = 3/1.5 = 2


AND ST/UV = 5.4/2.7 = 2


∴Δ RTS IS SIMILAR TO ΔRVU


SO, the best statement is:


Each pair of sides corresponds with a common ratio of 2.
