Point | Marks a location. It has no dimension. It is represented by a dot. It is named by a capital letter. |
Line | It has one dimension. It is represented by a line with two arrowheads over two capital letters representing points on the line. It extends without end. Through any two points, there is exactly one line. |
Plane | It has two dimensions. It is represented by a parallelogram. It can be named by a capital letter not representing a point or three non-collinear points. It extends without end. Through any three non-collinear points there exists exactly one plane. |
Collinear | Geometric objects sharing the same line |
Coplanar | Geometric objects sharing the same plane |
Non-collinear | Geometric objects that do NOT share the same line |
Non-coplanar | Geometric objects that do NOT share the same plane |
Endpoint | The point that marks the beginning or end of a geometric object. |
Line Segment | Part of a line that has one dimension, a definite start point and a definite end point. |
Ray | Part of a line that has one dimension, a definitie start point but no end point. |
Opposite Rays | Two rays that have the same start point but go in opposite directions |
Intersection | The point or line where two geometric objects meet |
