Hello. For this question, I have included a diagram to better illustrate my approach. I think the book may be incorrect, as the point m would be some way off from where it would need to be in order to form a parallelogram. Can anyone help me confirm if I have this right or not? Many thanks.

The graph looks like this. (Use the scroll bar to see the entire diagram.) Code:  m o  * * *  * * *     o    *             * *  * o k  * *  * *  * *  o h
