Depending on which sides and angle are known you would use one of the trigonometry functions.

Not the best way of finding out if a triangle is right angled. But if you can find two if the sides which have gradients which when multiplied together gives -1, then the angle between them is a right-angle. This comes from the fact that if the slope of a line is a/b, then the slope of a perpendicular line is -b/a and the product of (a/b)(-b/a)=-1.
