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.
The midsegment of a trapezoid has two special properties: 1  The midsegment of a trapezoid is parallel to each base. 2  The length of the midsegment of a trapezoid is equal to half the sum of the lengths of its bases.
