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

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

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 _____ = ____ + _____ (draw a diagram) 16. SR = 4, RT = 6, ST = _____ 17. SR = 19, ST = 41, RT = ____ 18. RS = 2x, RT = 4x+10, ST=9x-5. Find x, RS, TR, ST 19. RS = 2x-1, TR = 5x+2, ST=10x-8. Find RT. 20. RS = x, RT =3x-11, TS=2x+3. Find ST.
