Identify Points, Lines, and Planes

6.1 Points, Lines, and Planes.

Wadima's group

Learning Outcome:

• 1. Identify and model points, lines, and planes.

• 2. Identify intersecting

  lines and planes.

Definitions

• Point, line and plane are considered undefined terms because they are only explained using examples and descriptions.

• Point is a location, it's neither shape nor size.

• Line is made up of points and it has no thickness or width, there is exactly one line through any two points.

• Plane is a flat surface made up of points that extends infinitely in all directions.

• There is exactly one plane through any three points that are not on the same line.

• Collinear points are points that lie in the same line.

• Noncollinear points do not lie of the same line.

• Coplanar points are points that lie on the same plane.

• Noncoplanar points are points that do not lie on the same plane.

• The intersection of two or more geometric figures is the set of points they have in common.

• Definitions or defined terms are explained using undefined terms and/or other defined terms

• Spaced is defined as a boundless, three-dimensional set of all points. space can contain lines and planes
