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.

  1. 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

  2. Example 9 15 B B C C A A If AB=9 and BC=15, find AC. AC=9+15=24 If AB=8 and BC=3, find AC. AC=8+3=11

  3. Example • Example 1: If DT = 60, find the value of , then find DS and ST. D S T

  4. Example: • EG =100. Find , then find EF and FG. F G E
