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 side of the triangle that the midsegment does not intersect is the base of the triangle. The midsegment of a trapezoid is the segment formed by connecting the midpoints of the two legs of a trapezoid. Although the midsegment of a trapezoid is also useful in mathematics, we will not discuss it here.
