1. Recall the property of a midpoint:

If a point is the midpoint of a line segment , then it divides the line segment into two congruent sub - segments. That is, .

Also, by the segment addition postulate, for three collinear points , , and , .

Since and , we can substitute with in the equation . So we have .
