What is a quadrilateral with four sides?
If you connect the four linear objects at their eight ends, you have a quadrilateral, a four-sided polygon. Maybe you arranged four sides so the shape looks full, which means you made a convex quadrilateral. Maybe your four line segments made a pointy shape like an arrowhead; you made a concave quadrilateral.
