If hypotenuse^2 = leg1^2 + leg2^2 you know you
have a right angle across from the hypotenuse.

But Pythagoras is not a tool to calculate angle sizes.
It is a tool to calculate side sizes.

You cannot use the Pythagorean theorem with angles, because
the Pythagorean theorem is for sides only. To calculate with
angles or to find angles, you must use trigonometric ratios,
such as "sine", "cosine" and "tangent".

You don't. The Pythagorean Theorem provides a relationship between the measures of the three sides of a right triangle. To show the relationship between the measure of the sides of a right triangle and the two acute angles of the triangle, you need to use the sine, cosine, and tangent trigonometric functions.
