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.
The equivalence of this definition with the earlier one is often called the subgroup condition. For full proof, refer: Sufficiency of subgroup condition. It has two forms (left and right): A subset of a group is termed a subgroup if it is nonempty and is closed under the left quotient of elements. In other words, a subset of a group is termed a subgroup if and only if is nonempty and whenever. A subset of a group is termed a subgroup if it is nonempty and is closed under the right quotient of elements.
