Segment Addition Postulate

Segment Addition Postulate. If three points (A, B, and C) are collinear and B is between A and C, then AB + BC = AC. In other words: If three points are on a line, then the length of the 2 segments created can be added together to get the length of the entire segment!. A. B. C. Example. 9.
