The side opposite to the right angle is called the hypotenuse (side c in the figure). The sides adjacent to the right angle are called legs (or catheti, singular: cathetus). WebWhen the angle C is right, it becomes the Pythagorean formula. The law of sines says that the ratio of the sine of one angle to the opposite side is the same ratio for all three angles. With these two formulas you can solve any triangle: If you know two angles and a side, you can find the third angle and the other two sides.
