This looks like a great first project for the Fireball Comet. The famous Pythagorean Theorem states that if $latexa$ and $latexb$ are the lengths of two legs of a right triangle and $latexc$ is the length of the hypotenuse, then

$latex{a}^2+b^2=c^2.$

This puzzle demonstrates this theorem, by challenging the solver to make a square with area $latex{c}^2$ using the pieces taken from the two squares with areas $latex{a}^2$ and $latex{b}^2$.
