Points Lines & Planes in Geometry

I introduce Points, Lines, and Planes along with many definitions like collinear and coplanar points to begin our studies of Geometry. Parts D and E of the last example should read is there a plane in the solid that contains these 3 vertices, not if they are coplanar. Asking if they are coplanar is the same type of error I corrected early in the video. Three points define a plane.
