Distance
1. How far apart two things are.2. The absolute value of the difference of
the coordinates of the point1. A is at coordinate 12. B is at coordinate 83. The distance between A and B is:
Which equals?
8-1

Between
When 3 points are collinear then the point in the middle is “between” the other two B is between A and CA B C

Congruent Segments
Line segments that have the same length are congruent segments.

Ruler Postulate
The points on a line can be matched one to one with the real numbers. Giving them coordinates
Using their coordinates, we can find the distance between the points
A=0 B=3 C=5 D=10
