Answer:
Step-by-step explanation:
Properties of the similarity of two triangles,
1). Corresponding angles of two triangles should be equal.
2). Corresponding sides of two triangles should be proportional.
By applying second property in the given triangles RTY and CVB,
Ratio of sides CB and RY should be 1.5 for the similarity of two triangles.
Therefore, additional information required for the similarity of two triangles is "the measure of third sides of both the triangles should be known"
