What have you learned? Drawing and labeling points, lines, rays, segments and parallel lines.
Through any two points there is EXACTLY one line.
Two lines intersect in exactly ONE POINT.
Two planes intersect in exactly ONE LINE
Any three noncollinear points is exactly one plane.
Parallel lines never touch and are in the same plane.
Skew lines never touch but are NOT in the same plane.
