Undefined Terms Points, Lines, and Planes 1 basic ideas that can be used to build definitions of all other figures in Geometry Point *indicates a location *has no size *represented by a dot *NOTATION: Point A A
Point *indicates a location *has no size *represented by a dot NOTATION: Point A A Line *a straight path that extends in two opposite directions *no thickness *never ends *lines contain infinitely many points NOTATION: AB BA BC CB AC CA line l m A B C
Plane *a flat surface *extends in all directions *never ends *contains infinitely many lines NOTATION: -Plane ABC (at least 3 points that are not in a line) -Plane P A B C P -Plane ABCD, BCDA, CDAB, DABC, etc. A B D C
Space The set all all points in three dimensions. Collinear Points Points that lie on the same line A B C Noncollinear Points Points that don't lie on the same line B A C
Coplanar Points and lines that lie in the same plane A B C P Noncoplanar Points and lines that don't lie in the same plane A B C D
Intersection The set of points that two figures have in common two lines two planes a line and a plane
Contains One figure is completely inside of the other. Plane M contains point P and line k line j is NOT contained in plane M
