1. 1.2 Measuring and Constructing Segments

2. _Postulates__ or axioms - statements or ideas that are accepted without proof
_Theorems_ - statements that must be proven
A point corresponds to one and only one number called a _coordinate__.

3. The _distance__ between any two points is the absolute value of the difference of the coordinates
The distance between two points is called the __length_.
__congruent segments__ are segments that have the same length. The symbol for congruence is _____ but can also be written with tick marks.

4. A _midpoint__ is exactly halfway between two other points
__Bisect__ means to cut into two congruent pieces
___Segment bisector___ is any ray, segment, or line, that intersects a segment at its midpoint.

6. Use the Ruler Postulate to find AB.

10. Suppose J is between H and K. Find JK.
HJ = 5x ; JK = 7x ; HK = 96

11. Suppose J is between H and K. Find JK.
HJ = 2x + 5 ; JK = 3x - 7 ; HK = 18

12. Suppose J is between H and K. Find JK.
HJ = 6x - 5 ; JK = 4x - 6; HK = 129

13. Write the Segment Addition Postulate if X is between M and A.
