The best way to explain a process is to first follow the process yourself! Follow

these instructions to design your own string of pennant flags.

1. Choose a room you would like to decorate. Measure its length or width. This
   

measurement will be the length of your pennant string.

1. Choose a size of paper square to use. (Hint: Whole number side lengths will
   

make the calculations easier.)

1. Cut the square in half along the diagonal to form two paper triangles
   

(pennant flags).

1. Measure the length of the diagonal. Then use the Pythagorean Theorem to
   

find its exact length.

1. You will attach each triangle to the string along its diagonal side, with no
   

space between triangles. Divide the length of the string by the length of the

diagonal to determine how many triangles you will need.
