  1. GEOMETRY: CHAPTER 1 Ch. 1.5 Segment and Angle Bisectors

  2. Midpoint—The midpoint of a segment is the point that divides the segment into two congruent segments. A segment bisector is a point, ray, line, line segment, or plane that intersects the segment at its midpoint. A midpoint or a segment bisector bisects a segment.

  3. Ex. 1

  4. The Midpoint Formula (p. 16) The Midpoint Formula The midpoint of the line segment joining the points A(x1,y1) and B (x2,y2) is given by the Midpoint Formula. Midpoint =

  5. Ex. 2 Use the Midpoint Formula to find that M is (1,1)
