6.4 The Triangle Midsegment Theorem Using the Midsegment of a triangle What do you think a midsegment is? A midsegment of a triangle is a segment that connects the midpoints of two sides of the triangle. EVERY triangle has three midsegments, which form the midsegment triangle. Example 1: Using midsegments in the coordinate plane In triangle JKL, show that midsegment MN is parallel to JL and that MN= ½ JL
