In mathematics, Niven's theorem, named after Ivan Niven, states that the only rational values of θ in the interval 0° ≤ θ ≤ 90° for which the sine of θ degrees is also a rational number are: Visa mer • Pythagorean triples form right triangles where the trigonometric functions will always take rational values, though the acute angles are not rational • Trigonometric functions Visa mer • Weisstein, Eric W.
