A standard piece of wood (one that can be found at just about any wood store), is cut with two straight cuts. After being cut, the wood will fit perfectly through three holes: circle, square, and triangle. What piece of wood was used, and how was it cut?

With two complimentary cuts, each at opposing 30 degree angles. The circle remains as the original shape of the dowel. The equilateral triangle is formed by the 60 degree angle at the apex. The square is formed by looking at the broadest side of the section.
