8. Measuring Segments D F A

9. Postulate 1-5 "Ruler Postulate" point Every ________ on a line can be paired with a real number called the coordinate of the __________. point Remember to add to notes and postulate sheet What do this really mean? We can measure the distance between points using a ruler or the coordinates (locations) or the points. Lets look at a few examples.

10. Ex. What is ST? S R T V 10 8 9 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 B A Distance Formula: a b AB = |a - b| Now lets try for ST.

11. S R T V 10 8 9 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 ST = 12 RT = ? TV = ? What is RV?

12. Congruent Congruent When two segments have the same length, they are called _____________ The geometric symbol for congruence is ______ C A B

13. Postulate 1-6 "Segment Addition Postulate" If three __________ A, B, and C are collinear and B is between A and C, then AB + BC = AC A B C

14. Ex. If EG = 59, what are EF and FG? G E F 4x + 1 8x - 14 EF + FG = EG 8x - 14 = EF 4x + 1 = FG 8(6) -14 = EF 4(6) +1 = FG (8x - 14) + (4x + 1) = 59 48 -14 = EF 24 + 1 = FG 12x - 13 = 59 34 = EF 25 = FG 12x = 72 x = 6

15. Ex. In the diagram, JL = 120. What are JK and KL? * J K L 7x +15 4x + 6 JK + KL = JL 4x + 6 = JK 7x +15 = KL (4x + 6) + (7x +15) = 120 4(9) +6 = JK 7(9) +15 = KL 11x + 21 = 120 36 + 6 = JK 63 +15 = KL 42 = JK 11x = 99 78 = KL x = 9

16. Finish examples 4 and 5 in your notes.
