You will see that there is a minimum angle of deviation, about 37.2 degrees. If you drag the prism either direction from orientation that gives this minimum deviation, you find that the deviation is quite insensitive to the change. That is just a familiar fact of calculus: at a minimum, the derivative is zero.
