Hinge Theorem

Move the slider to change the angle. Notice how the two sides adjacent to the angle don't change, but something else does.
As the angle gets bigger, what else changes with it? Does it get larger or smaller? As the angle gets smaller, what else changes with it? Does it get larger or smaller? Can we use the angles of a triangle to make a prediction about the relative lengths of the opposite sides?
