Lines and Segments SY 2015-2016 Source: Geometry (2007) by Ron Larson et al
2
Definitions O Line Segment: is a subset of a line that contains two points (called the endpoints) and all points in between them.
3
Definitions O Between-ness
4
Postulate
5
Try this! Which segments are coplanar? Is AB + BC = AC ? Why or why not?
6
Try this! Solve for the unknowns.
7
Try this! Solve for BD if AB = BC, AC = DC, and AD = 12.
8
Try this! O Always, Sometimes, Never. If CA = AT, then A is the midpoint of CT.
9
Try this! Solve. Points A, B, C, D, E are collinear points. Point B is the midpoint of AE. Point D is the midpoint of BE. C is between points A & B. If BD = 3cm & CE = 7cm, then how long is AC?
10
Try this! True or False. Point D is a midpoint in the figure. C D A B
