Henry Ernest Dudeney/Modern Puzzles/109 - Squaring a Star

by : $109$

 * Squaring a Star
 * This six-pointed star can be cut into as few as five pieces that will fit together to form a perfect square.
 * To perform the feat in $7$ pieces is quite easy,
 * but to do it in $5$ is more difficult.

 * The dotted lines are there to show the true shape of the star, which is made of $12$ equilateral triangles.
