A Penny Apiece
 
Q Cut a big circle out of a sheet of paper. Place seven pennies on the paper circle as follows:
  1. Place six pennies, evenly spaced, around the outer edge of the circle. Label the top penny "A," and the others, "B," "C," "D," "E," and "F," going clockwise around the circle.
  2. Place one penny in the middle of the circle. Label it "G."
Now divide the circle into sections by drawing three straight lines so that there is only one penny in each section.


 
A Begin by drawing a horizontal line across the circle, just below penny G.

Next, draw a diagonal line beginning just to the left of penny A, passing to the right of penny G, and just beneath penny C.

Then draw another diagonal line beginning just to the right of penny A, passing to the left of penny G, and just beneath penny E.

Penny G should end up in a small triangle all by itself.
