A. Vocabulary:
1. A point is a geometric figure with no set size.
The Hershey Kiss is a POINT on the line
It is named by a capital letter.
2. A line is a geometric figure consisting of points extending in two direction without ending.
It is named by two points on the line or a lowercase italicized letter. h l C D A B

There is exactly one plane through any three noncollinear points A B C M
Plane M or plane ABC

5. 4. A space is the set of all points.
5. A collinear points are points all in one line.
6. A noncollinear points are points not all in one line.
7. Coplanar points are points all in one plane.
8. Noncoplanar points are points not all in one plane.
