Midsegments of Triangles Math 2 - Lesson 24 Mr. Lopez
Midsegment • The midsegment of a triangle is the segment connecting the midpoints of two sides. • Midsegment Theorem: • If a segment joins the midpoints of two sides of a triangle, then: • the segment is parallel to the third side • and it’s half the length of the parallel side
Practice • In EFG, H, J, and K are midpoints. Find the lengths of HJ, JK, and FG. F 60 J H 40 E G K 100
