Finding lengths of a triangle with angles
WebSep 15, 2024 · Theorem 2.5. For any triangle ABC, the radius R of its circumscribed circle is given by: 2R = a sinA = b sin B = c sin C. Note: For a circle of diameter 1, this means a = sin A, b = sinB, and c = sinC .) To prove this, let O be the center of the circumscribed circle for a triangle ABC. WebJul 4, 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.
