The task is to prove that the line segment joining the midpoints of two sides of a triangle is parallel to the third side and half as long. (Or in vector notation PQ = AB / 2). It should be proved using some vector algebra but I am not sure how to go about doing it. A (crude) visualization:enter image description here
