If you know the side lengths of a right triangle, can you pretict what the angles will be?

Lengths: Angles:
AC = 9 A = 45
BC = 9 B = 45

AC = 6 A = 56.31
BC = 9 B = 33.69

AC = 9 A = 29.05
BC = 5 B = 60.95

i noticed that when i changed one of the side lengths of the triangles, the other side length didn't change. on the website, http://www.shodor.org/interactivate/activities/SquaringTheTriangle/,when i changed the side length AC, length BC stayed the same. i noticed that when i changed the side length AC, angle A increases and Angle B decreases. When i increased side BC angle B increased and angle A decreased.

    So the other side stays the same; what about the hypotenuse? Does it change? If so, how? Do the angles change in any predictable way? You probably need to collect more data before you will be able to see any patterns.
