1. Points, Lines, and Planes
1-1

2. Objectives
• Use geometric concepts and properties to
solve problems
• Identify and model points, lines, and planes.
• Identify intersection lines and planes
• Use numeric and geometric patters to make
generalizations about geometric properties
including properties of polygons

3. Vocabulary Words
• Undefined terms- only explained using
examples and descriptives
• Point- is a location; neither shape nor size
• Line- made up of points and has no thickness
or width. There is exactly one line through any
two points
• Plane- a flat surface made up of points that
extends infinitely in all directions

• Collinear Points- Points that lie on the same line
• Coplanar Points- Points that lie on the same plane
• Noncoplanar Points- Points that do not lie on the
same plane

8. Vocabulary

the set of points they have in common
