Answer:
B. =
=
, must be true.
Step-by-step explanation:
Similar figures are figures whose angles and sides are similar with respect to a definite ratio when compared.
From the given question, note that ΔRXY is within ΔRST. Given that the two triangles are similar, then their sides can be compare in a form of ratio as:
=
=
Therefore by comparing the length of sides of the triangles, option B must be true.
