Collinear Points Definition: Collinear points are points that lie on the same line. (The line does not have to be visible. ) collinear non-collinear

Lines How to sketch: n * must have arrows at both ends ? ?

Lines How to sketch: n * must have arrows at both ends ? ? ? How to label: (Two methods) 1 - small “script” letter 2 - any two points on the line Possible Names:

Planes horizontal “edges” How to sketch: * horizontal * vertical * other M P

Planes horizontal “edges” How to sketch: * horizontal * vertical * other M P N How to label: (Two methods) 1 - capital “script” letter 2 - any three points on the plane vertical “edges”
