  1. 1-3Measuring Segments Objective: To find and compare lengths of segments

  2. Measuring segment lengths The distance between points A and B is the absolute value of the difference of their coordinates, or .

  3. What is SV? S T V U remember 0 2 4 6 8 10 -4 -2 -8 -6 -10 SV= = = 4

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

  5. Remember… • Midpoint • A point that divides the segment into two congruent segments Midpoint O N M l Segment Bisector A point, line, ray or other segment that intersects a segment at its midpoint is said to bisect the segment . That point, line, ray or segment is called a segment bisector. l is the segment bisector of .

  6. Using the Midpoint p. 23: 1-4, 9-21 odd Sooo….. PQ and QR are both 41. PR is 82.
