By creating a regular pentagon and drawing in the diagonals, a star called a pentagram is formed. You can find the golden ratio in a pentagram. If you can tie a knot, you can make a regular pentagon using a strip of paper. Cut a strip of paper inch wide and 11 inches long. Fold a knot in the paper, carefully tighten it, and gently flatten until the regular pentagon is formed. Cut or fold over the excess paper.

Draw in each diagonal of the regular pentagon.

a. Carefully measure the length of a diagonal, in inches, and convert the measurement to a decimal. See the bold segment in figure (a). How does the number compare to f?

b. Carefully measure the distance from a point of the pentagram to a flat side, in inches, and convert the measurement to a decimal. See the bold segment in figure (b). How does this number compare to
