A Mathematical System

These are points that lie on the same plane.

• Skew lines

• coplanar

• Plane

• Intersecting Planes

its refers to the portion of a line that has two endpoints.

• Ray

• Line

• Segment

• Point

it is a two lines that intersect forming congruent right angles.

• Perpendicular Lines

• Intersecting Lines

• Vertical Line

• Angle

refers to the portion of a line that has

one endpoint and it is named

by the endpoint.

• Point

• Segment

• Opposite Rays

• Ray

These are points that lie on

the same line.

• Plane

• Coplanar

• Collinear

• Parallel Planes

Two rays that have a

common endpoint that point

in opposite directions.

• Opposite Rays

• Ray

• Segment

• Opposite Angle

These are planes that have

no common point.

• Parallel

• Parallel Lines

• Plane

• Parallel Planes

These are planes that have a

common line, examples are

ceiling and wall.

• Plane

• Parallel planes

• Intersecting Planes

• Plane Geometry

Two lines with a common

point.

• Intersecting Lines

• Parallel Lines

• Perpendicular Lines

• Skew Lines

These are two lines that are

not in the same plane.

• Skew Lines

• Coplanar

• Collinear

• Parallel Planes
