Try to draw k4 twice once with at least two edges crossing

Question

Question: 1. Try to draw K₄ twice, once with at least two edges crossing and once with no edges crossing. Can you do it?

2. Try to draw K₅ twice, once with at least two edges crossing and once with no edges crossing. Can you do it?

3. In the standard way of drawing K_m,n, one draws m dots in a row and, a bit below this row, draws another n dots in a row. Then one connects each of the m dots to each of the n dots. Make a standard drawing of K_2,4. Do you think there is a different drawing of K_2,4 with no edges crossing?
