WebT HE LAW OF SINES allows us to solve triangles that are not right-angled, and are called oblique triangles. It states the following: The sides of a triangle are to one another in the same ratio as the sines of their opposite angles. a: b: c = sin A : sin B : sin C. Specifically, side a is to side b as the sine of angle A is to the sine of angle B.
