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.
Prove theorems about triangles. Theorems include: measures of interior. angles of a triangle sum to 180 degrees; base angles of isosceles triangles are congruent; the. segment joining midpoints of two sides of a triangle is parallel to the third side and half the. length; the medians of a triangle meet at a point.
