Lesson 1.2 Linear Measurement

Line Segment – has 2 endpoints. Can be measured. - Named by the 2 letters that are the endpoints with a bar on top.

Between – point that is collinear with 2 or more other points Between – point that is collinear with 2 or more other points. Not necessarily in the middle. Ex. M is between A and B. AM = 15, MB = 10. Find AB. Ex. Find y and PQ if P is between Q and R, PQ = 2y, QR = 3y + 1, PR = 21

3. Congruent – two or more segments having the same length
