Online calculators, using the sine law, to solve triangle problems. The first calculator solves triangle problems when 2 angles and one side opposite one of the angles are given (AAS case). The second calculator solves triangle problems when 2 angles and one side between the two angles are given (ASA case). The third calculator solves triangle problems when 2 sides and one angle opposite one of the sides are given (SSA case).
1  Solve Triangle Problems When 2 Angles and one Opposite Side are Given (AAS case)How to use the calculator
Enter the 2 angles A and B (in DEGREES) and side a (opposite angle A) as positive real numbers and press "enter". The outputs are sides b and c and angle C in DEGREES.
2  Solve Triangle Problems when 2 Angles and one Side Between them are Given (ASA case)How to use the calculator
Enter angles A and B (in DEGREES) and side c as positive real numbers and press "enter". The outputs are sides a and b and angle C in DEGREES.
3  Solve Triangle Problems when 2 Sides and one opposite Angle are Given (SSA case)How to use the calculator
Enter sides a and b and angle in A (in DEGREES) as positive real numbers and press "enter". The outputs are side c and angles B and C in DEGREES.
NOTE: These problems might have one, two solutions or no solutions. This is called the ambiguous case.
