A midsegment of a triangle is a segment connecting the midpoints of two of its sides. Examples: Midsegment Theorem – If a line segment joins the midpoint of two sides of a triangle and is parallel to the third side, then the length of the line segment is half the length of the third side. Strategy: 1) Carefully graph the triangle.
