Triangles side length rule
WebJan 11, 2024 · A 30-60-90 degree triangle is a special right triangle, so it's side lengths are always consistent with each other. The ratio of the sides follow the 30-60-90 triangle ratio: 1:2:\sqrt {3} 1: 2: 3. Short side (opposite the 30 degree angle) = x. Hypotenuse (opposite the 90 degree angle) = 2x. Long side (opposite the 60 degree angle) = x√3. WebWhen the lengths of the sides of a triangle are known, the Pythagorean Theorem can be used to determine whether or not the triangle is an acute triangle. For a right triangle with a hypotenuse of length c and leg lengths …
