Rule of triangle side lengths

Webb4 juli 2024 · The side opposite the 30° angle is half of a side of the equilateral triangle, and hence half of the hypotenuse of the 30-60-90 triangle. The length of the remaining side follows via the Pythagorean Theorem. “And I take the triangle COY with angles 30-60-90. Since OC = 1, then OY = (√3)/2, and CY = 1/2.
