[color=#202122][size=3]Another by rearrangement is given by the middle animation. A large square is formed with area [/size][/color][color=#202122][size=4]c[sup][size=3]2[/size][/sup][/size][/color][color=#202122][size=3], from four identical right triangles with sides [/size][/color][color=#202122][size=4]a[/size][/color][color=#202122][size=3], [/size][/color][color=#202122][size=4]b[/size][/color][color=#202122][size=3] and [/size][/color][color=#202122][size=4]c[/size][/color][color=#202122][size=3], fitted around a small central square. Then two rectangles are formed with sides [/size][/color][color=#202122][size=4]a[/size][/color][color=#202122][size=3] and [/size][/color][color=#202122][size=4]b[/size][/color][color=#202122][size=3] by moving the triangles. Combining the smaller square with these rectangles produces two squares of areas [/size][/color][color=#202122][size=4]a[sup][size=3]2[/size][/sup][/size][/color][color=#202122][size=3] and [/size][/color][color=#202122][size=4]b[sup][size=3]2[/size][/sup][/size][/color][color=#202122][size=3], which must have the same area as the initial large square[/size][/color]
