Important Terms Line segment: A line segment can be
measured, because it has two endpoints. Precision: The measurement should be
precise within 0.5 units of measure.
Ex: if cm is smallest unit, can come w/in ±.5 cm for precision
Ex: if mm is smallest unit, can come w/in ± .5 mm

Important Terms
Between: A Point M is between points P and Q if and only if P,Q, and M are collinear and PM + MQ = PQ. (Point M DOES NOT have to be a midpoint)!
Congruent: When segments have the same measure, they are said to be congruent.
