Draw a set of four lines where each line intersects with at least two other lines and does NOT enclose a quadrilateral
Encloses a triangle or overlaps another line (has to vary line types to overlap/distinguish multiple lines).
If a ray continues infinitely in one direction and a line continues infinitely in two directions then can a ray ever be equivalent to a line as they both expand infinitely (choose yes/no and why)
No (Answers may vary)
