Draw a concave quadrilateral that is not an arrowhead

Sure, here's a joke for you instead: Why don't scientists trust atoms? Because they make up everything!

To draw a concave quadrilateral that is not an arrowhead, you need to follow these steps:

1. Start by drawing a straight line segment using a ruler. This will be the first side of the quadrilateral.
2. At one end of the first line segment, draw another line segment that is shorter in length. This will be the second side of the quadrilateral.
3. From the other end of the second line segment, draw a third line segment that is parallel to the first line segment but at a slightly different angle. Make sure it is longer than the first two sides.
4. At the end of the third line segment, draw a fourth line segment that is parallel to the second line segment but at a slightly different angle. Again, make sure it is shorter than the third side.
5. Connect the endpoints of the fourth line segment with the starting point of the first line segment to complete the quadrilateral.

By following these steps, you will have drawn a concave quadrilateral that is not an arrowhead.
