a = b * SIN(α) / SIN(β) R = a / (2 * SIN(α)) c = SQRT( a^2 + b^2 - 2*a*b*COS([π] - α - β)) A = 1/2 * b * c * SIN(α) s = 1/2 * (a + b + c) ri = A / s
"R" means the radius of the circumscribed circle of the triangle and "A" means the area of the triangle. " ri " stands for the radius of the inner circle of the triangle. "s" means half of the perimeter of the triangle.
