Midsegment Theorem Proof. The mid segment theorem states that a segment that connects the mid points of any two sides is parallel to the third side and also its measure is half the measure of the third side. That is, DE ll AB and DE = $\frac{1}{2}$ AB. Therefore, CA = CD + DA = 2 CD.
Betweenness Theorem. If a point is between two endpoints of a line segment, you can add the distance from the point to. one endpoint of the line segment to the distance from the point to the other endpoint of the line. segment to get the length of the line segment. Segment Addition Postulate. If B is between A and C, then AB + BC = AC.
