Let us say we want to find the square root of some length, GH. First, draw a line segment FG which is one unit long. Next, locate K, which is the midpoint of FH. Draw a semicircle with a center of K and FH as a diameter. Finally, draw a line perpendicular to FH through G. The length of IG will be the square root of the length of GH.
Kunt u met Algebra bewijzen dat dit laatste inderdaad zo is?
