Given

Triangle with midsegment

Procedure

A line segment that connects two midpoints of the sides of a triangle is called a midsegment.

First relation

[tex]DE=\frac{1}{2}BC[/tex]

Second relation

[tex]DE\Vert CB[/tex]

Conclusion: If the midpoints of any two sides of a triangle are joined by a segment, then that segment is parallel to the third side and half its length.
