This set of guided notes is a great introduction to Euclidean Geometry and the three undefined terms: points, lines, and planes. The front sides stresses the importance of notation and being able to look at geometric diagrams properly. The back allows you to introduce the concepts of collinear and coplanar points and a space to try to draw your own intersecting planes.
The answers are included!
