Observe that the square of side c ( with area c² )
is made up of 4 right triangles and 
one small square inside...
Now in the slider below,
move the slider button to right extreme 
to see that this bigger square gets changed into 
two squares with areas  a² and b².
thus a² + b²  = c² in  right triangle
