Understanding Right Triangle Angles
A right triangle is a triangle with one angle measuring exactly 90 degrees, known as the right angle. The sides adjacent to the right angle are called legs (Side A and Side B in our calculator), and the side opposite the right angle is the hypotenuse. This calculator helps you find the other two angles if you provide the lengths of the two legs. The angles are calculated using trigonometric functions, specifically the arctangent (atan) function, which relates the ratio of the sides to the angles in a right triangle. Remember, the sum of angles in any triangle is always 180 degrees, and in a right triangle, one angle is already 90 degrees.
