Question

In Triangle ABC, S is the midpoint of line segment AB and T and the midpoint if line segment AC, if AS = 6, CT = 8, and ST = 7, the permeter of ABC = 42?
in triangle ABC, S is the midpoint of line segment AC and R is the midpoint of BC. If AC = 18, BC = 22 and AB = 16 then RS =8?, ST = 11? and RT = 9?

Answer 1

In the first question your conjecture is true. In the second question you have not defined the point T, therefore we are unable to answer in this case. Conjecture concerning RS is correct.
