1.2 Linear Measure and Precision Goals: - Measure segments and determine accuracy of measurement - Compute with measures Line Segment (segment) Is made up of Points Located Between 2 pts called end points Can be measured The measure of Segment AB is written as: (always includes the units) AB Precision Smallest unit available on measuring tool Should be Precise to within .5 unit of measure What is potential range for AB? Discuss What is potential range for CD? Congruent Segments When 2 segments have same measure A Geometric Statement * Use tick marks on diagram to show congruence Go Back to beginning examples. Betweenness of points: Point C is between points A and B if and only if A, B, and C are collinear and AC+BC=AB When is C Not Between A and B? Find ST if T is between S and U, ST = 7x, SU = 45, and TU = 5x - 3 Draw out pic. Show steps.
