1.2 Linear Measure Learning Goals: Students will use the Segment Addition Postulate. Homework: Page 16 # 3, 4, 15-22, 29
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.
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
Congruence AB + BC = AC Congruent – Two segments Segment Addition Congruent – Two segments having the same measure. AB + BC = AC
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
