  3. Postulate Rules that do not have to be proved ( axiom ) Postulate 1 Ruler Postulate • A Points on a line can be matched to their real numbers. • B Names Ex 1 x1 x2 Coordinates

  4. 4 11 The absolute value of the difference between A and B Distance ( Length ) • A Length of AB is │x2 – x1│ • B │11 – 4 │ 7

  5. Ex 2 │2 – 6.5 │ • C • D │ - 4.5 │ 4.5

  6. P 2 Segment Addition Postulate. If B is between A and C, then AB +BC= AC If AB +BC= AC, then B is between A and C • C AC • A • B AB BC

  7. 17 Ex 3 • C 5 AB • A Find AB AB + 5 = 17 • B AB = 17 - 5 AB = 12

  8. Do 1 What is the distance between Kingman and Phoenix? • • • A M B Kingman Phoenix Tucson AB = 430 miles MB = 141 miles

  9. Ex 4 Find x, LM, MN, LN 23 • N 3x + 8 2x - 5 • L Find x 3x + 8 + 2x - 5 = 23 • M 5x + 3 = 23 5x = 23 - 3 5x = 20 x = 4

  10. x = 4 23 • N 3x + 8 2x - 5 • L Find LM 3x + 8 • M 3( 4 ) + 8 12 + 8 20

  11. Review What is absolute value? • N 23 Do 2 Find MN • L 3x + 8 2x - 5 • M Textbook page 21, 19 – 33 all. Assignment
