Use the figure below to complete the following problem. given: r, s, t are midpoints of ac, ab, and cb. rs = 1/2cb 1/2rt 1/2ab

Let points R, S, T be the midpoints of segments AC, AB, and CB.

Triangle midline theorem states that the line segment connecting the midpoints of two sides of a triangle is parallel to and half the length of the third side.

Thus, the midline RS (where R is a midpoint of AC and S is the midpoint of AB) is parallel to BC and is half the length of the side BC:

correct choice is A
