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.
Definition: A chord is a segment whose endpoints lie on a circle. Theorem: If a line through the center of a circle is perpendicular to a chord, it bisects the chord. Theorem: In the same circle or in congruent circles, if two chord are the same distance from the center, then the chords are congruent.
