The classic Pythagorean Theorem states the sum of the squares on the legs of a triangle is equivalent to the square on the hypotenuse or [math]a^2 + b^2 = c^2[/math]. [br]You can adjust the lengths of sides [color=#ff0000][b]a[/b][/color] and [color=#0000ff][b]b[/b][/color] by moving the [color=#ff0000][b]red[/b][/color] or [color=#0000ff][b]blue[/b][/color] sliders.[br]The math for squares can shown by checking [b]Show Math[/b]. This is the common testable math.[br]Adjusting the [b]poly[/b] slider will show that the theorem works for other regular polygons, areas are show inside each polygon.[br]This app allow you to see that the sum of the area rule applies other regular polygons from 3-10 sides.[br]There is a Pythagorean Triple generator included with this app, ancient Babylonians posted many such triples about 1000 before Pythagoras.
