If triangle RST and triangle XYZ are similar, which of these equations must be true?
Delicious77 [7]

Answer: A

Step-by-step explanation:

If they are similar, that means the proportions for corresponding sides will be the same.

          I personally ignore the picture and use the labels of "triangle RST and triangle XYZ" that the problem gives <em>because</em> the XYZ picture is not lined up with the similarity it has with RST.

(A) says that side ST is corresponding with side YZ,

          [] Triangle R<u>ST</u> and triangle X<u>YZ</u>

          -> Correct

(A) also says that side RT is corresponding with size XZ,

          [] Triangle <u>R</u>S<u>T</u> and triangle <u>X</u>Y<u>Z</u>

          -> Correct

               This means that option A is the correct answer.
