WebThe ratio of the side lengths of a 30-60-90 triangle is 1 ∶ √3 ∶ 2. This means that if the shortest side, i.e., the side adjacent to the 60° angle, is of length 𝑎, then the length of the side adjacent to the 30° angle is 𝑎√3, and the length of the hypotenuse is 2𝑎. In this case we have 𝑎√3 = 15 ⇒ 𝑎 = 5√3. WebCorollary 3. The acute angles in a right triangle with rational side lengths are never rational multiples of π. Proof.
