Question

Use the figure below to complete the following problem. Given: R, S, T are midpoints of AC, AB, and CB. RS = ???

Answer 1

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:

$RS=\dfrac{1}{2}BC.$

Answer: correct choice is A
