1. 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. 1086 4 -10 -8 -6 2 -4-2 0 TS U V What is SV? SV = = = remember

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

5. Midpoint A point that divides the segment into two congruent segments Remember… O Midpoint M N l is the segment bisector of. 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

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