1. Warm-up 1.3x = 8x – 15 0 = 5x – 15 15 = 5x x = 3 2.6x + 3 = 8x – 14 3 = 2x – 14 17 = 2x x = 8.5 3.5x – 2 = 3x + 6 2x – 2 = 6 2x = 8 x = 4 AB = 2 AM AB = 2(5x – 2) AB = 2(5*4 – 2) = 2(18) AB = 36

2. 5.2: Use Perpendicular Bisectors A line segment (or line or ray) is a perpendicular bisector iff it is perpendicular to another segment at its midpoint

3. equidistant CB

4. AB 4x7x - 6 2 4x 4(2) 8

6. Check Points #1 and 2

9. Work these out now! 2x = 5x – 6 0 = 3x – 6 6 = 3x x = 2 AB = 4 3x + 8 = 7x – 16 8 = 4x – 16 24 = 4x x = 6 AB = 26 6x + 11 = 11x – 9 11 = 5x – 9 20 = 5x x = 4 AB = 35
