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.
In the trapezoid below, the midpoints of the non-parallel sides are points S and V. The midsegment is the red line segment from S to V. The midsegment below can be found by. calculating the lengths of the bases 35-16 = 9 (length of upper base) 45-0 =45 (length of lower base) calculating the sum of the bases 9+45 = 54.
