One of the two legs — the sides that form the right angle. Angle A is the acute angle opposite this leg.

The other leg of the right angle. From two legs the hypotenuse follows by Pythagoras: c = √(a² + b²).

The hypotenuse — the longest side, opposite the right angle. It must be longer than any given leg.

One of the two acute angles, in degrees, strictly between 0 and 90. It sits opposite leg a; the other acute angle is 90° − A.
