Draw a right triangle with legs of length and units, respectively, onto graph paper. Construct a square on the hypotenuse and use the square’s area to find the length of the hypotenuse.  

Draw the triangle and a square where one side is the hypotenuse.

Count the number of unit squares contained within the square, giving each partial square a value of one half.

Since the area of the square () is the length of the hypotenuse squared, the square root of the square's area is the length of the hypotenuse.
