Use midsegments of triangles in the coordinate plane. Use the Triangle Midsegment Theorem to fi nd distances. Using the Midsegment of a Triangle 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.
