2. 1.2 Linear Measure
Line segment – A measurable part of a line that consists of two points called endpoints and all of the points in between.

3. Example 1: Find each length
The long marks are centimeters, and the shorter marks are millimeters. There are 10 millimeters for each centimeter.
Each inch is divided into fourths
Example 2-1a

4. Congruence AB + BC = AC Congruent – Two segments
Segment Addition
Congruent – Two segments
having the same measure.
AB + BC = AC

5. Example 2: Example 3: Find LM.
Find x and ST if T is between S and U, ST = 7x, SU = 45, and TU = 5x – 3.
Example 2-4a
