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.
Theorems include: measures of interior angles of a triangle sum to 180Â°; 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. The student will: x prove that the sum of the measures of the interior angles of any triangle is 180 degrees. x prove that the base angles of an isosceles triangle are congruent. x prove that the segment joining the midpoints of two sides of a triangle is parallel to the third side and half the length of the third side. x prove that the medians of a triangle meet at a point. x use theorems about triangles to prove claims about geometric figures .
