Midsegment of a triangle is a segment that connects the midpoints of two sides of a triangle A D G B C O
Theorem 5.9 MidsegmentTheroem • The segment connecting the midpoints of two sides of a triangle is parallel to the third side and is half as long. A D G B C
Practice problems • Show that midsegment PQ is parallel to segment DE and half as long. • Segments JK and KL are midsegments of triangle ABC. Find JK and AB
