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.
1 The midsegment is parallel to the base. 2  The triangle formed by the midsegment and the two half sides have all the same angle measures as the original triangle.  The perimeter of the triangle formed by the midsegment and the two half sides is equal to one half the perimeter of the original triangle.
