GEOMETRY
CHAPTER 1
TOOLS OF GEOMETRY
1-3 Segments, Rays, Parallel
Lines and Planes
Objective: Relating segments and rays to lines;
recognizing parallel lines and planes
Segment

A
B
Ray
the part of a line consisting of one endpoint and all the points of the line on one side of the endpoint

2. Name a pair of opposite rays with W as the endpoint.
3. Give two names for the line.
True or False
4. UW = WU
True or False
5. UW = WU
Parallel Lines
coplanar lines that do not intersect
Skew Lines
- do NOT lie in the same plane
-are not parallel, are not intersecting
Parallel Planes
­­planes that do not intersect
