This applet shows a proof of the [color=#c51414]Pythagorean Theorem[/color] which states: for right triangles, the sum of the squares of the legs is equal to the square of the hypotenuse. Segments a and b are legs. The hypotenuse is side c. The default setting is a [color=#1551b5]3,4,5 triangle[/color] which is a [color=#c51414]Pythagorean Tripple[/color], which means the three sides are integers. Try [color=#1551b5]moving a vertex[/color] of the triangle and see how the new lengths fit into the equation. See if you can find another [color=#c51414]Pythagorean Tripple[/color].
