They want take a pencil, a paper and sketch by your hand an arbitrary quadrilateral
by marking its vertices as J, K, L and M, in precisely this order.
Then highlight its sides JK, KL, LM and MJ.
This exercise is as simple and inelaborate as a cucumber.
It looks strange when such simple task is posted to the forum for the tutors consideration,
instead of doing it silently without requesting for any help from outside. <<<--- as it SHOULD BE DONE.
There, all you need is a pencil and a straight-edge. It doesn't have to
look like my drawing. Just make sure that it is impossible to draw a line
through any three of your points.
