Also, the calculator will show you a step by step explanation. You could also use the Sum of Angles Rule to find the final angle once you know 2 of them. If a, b and c are the lengths of the legs of a triangle opposite to the angles A, B and C respectively; then the law of cosines states: a2 = c2 + b2 - 2bc cos A,   solving for cos A,   cos A = ( b2 + c2 - a2 ) / 2bc, b2 = a2 + c2 - 2ca cos B,   solving for cos B,   cos B = ( c2 + a2 - b2 ) / 2ca, c2 = b2 + a2 - 2ab cos C,   solving for cos C,   cos C = ( a2 + b2 - c2 ) / 2ab, Solving, for example, for an angle, A = cos-1 [ ( b2 + c2 - a2 ) / 2bc ], Triangle semi-perimeter, s = 0.5 * (a + b + c), Triangle area, K = √[ s*(s-a)*(s-b)*(s-c)], Radius of inscribed circle in the triangle, r = √[ (s-a)*(s-b)*(s-c) / s ], Radius of circumscribed circle around triangle, R = (abc) / (4K). Solve the triangle by entering one side and two adjacent angles (ASA law). The above diagram shows a typical case of solving a triangle when we are given two sides and one non-included angle. The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. Use the calculator above to calculate the area of a triangle given 2 sides and the angle between them. The lengths of the sides must be in the same unit. The SAS (Side-Angle-Side) postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent. Angle C and angle 3 cannot be entered. [1] In a triangle, all interior angles total to 180 degrees. Side of a parallelogram when diagonal and the angle between diagonals are given calculator uses Side=sqrt((Diagonal A)^2+(Diagonal B)^2+(2*Diagonal A*Diagonal B*Angle Between Two Diagonals))/2 to calculate the Side, Side of a parallelogram when diagonal and the angle between diagonals are given is the length of the side of the parallelogram.
