“Story Time…………. …” Length of a Segment (length = two capital letters) Number line Coordinate Plane

I. Length of a segment on a number line X A -310 -5 1. CE = 2. BA = 3. XA = B C 0 4. EA = 5. CB = 6. FX = E F 142 *what’s the rule?

II. Length of a Segment on a Coordinate Plane • Distance Formula- difference between two points on a coordinate plane Ex: Plot and label: A (2, 3), B (3, -1) and C(-4, 0). 13. AB = _____ BA = _____ 14. length BC = _____ 15. CA = ____ 16. True or False:

III. Segment Addition Postulate • If R is between S and T _____ = ____ + _____ 16. SR = 4, RT = 6, ST = _____ 17. SR = 19, ST = 41, RT = ____ 18. RS = 2 x, RT = 4 x+10, ST=9 x-5. Find x, RS, TR, ST 19. RS = 2 x-1, TR = 5 x+2, ST=10 x-8. Find RT. 20. RS = x, RT =3 x-11, TS=2 x+3. Find ST. (draw a diagram)
