Law of Sines

The law of sines states that a/sin A = b/sin B = c/sin C for any triangle. Given two angles and the side opposite one of them, this solver finds the third angle by the 180° rule and then the two remaining sides.

Frequently asked questions

What is the AAS case?

AAS means Angle-Angle-Side: two angles and a non-included side. The third angle follows from A + B + C = 180°.

Does this handle the ambiguous SSA case?

No. SSA (two sides and a non-included angle) can have zero, one or two solutions; this tool covers the unambiguous AAS case.

Which side should I enter?

Enter side a, the side opposite angle A. The solver finds the rest from the sine ratio.
