Hey drzombie123.

For this exercise its not computational: you need to use the physical piece of paper to get the mid-point. I haven't done this kinld of thing for a very long time, but if you have a ruler, then you can find the midpoint by placing the ruler along a specific line (HK for example is the line formed from drawing a straight line from point H to point K) and then finding the point where it divides the line into equal lengths.

If you have learned how to do this with a compass then you will want to use this to check your work.

So as an example: if you put your ruler against the line HK and you find its say 4 inches, then the mid-point will be 2 inches along that same line from either points H or K.
