Then change the angle say, 30 you will get another one. For almost all angles,there will be a possibility, I think.

And 0 possibility when the triangle can't be drawn, but I cannot say when the triangle cannot be drawn, can anybody? Maybe in cases like the sides are equal, but the angle greater than or equal to 90, right
