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. WebThe Sine Rule can be used in any triangle (not just right-angled triangles) where a side and its opposite angle are known. ... These examples illustrate the decision-making process for a variety of triangles: e.g. 1: The triangle is not right-angled. We do know a side and its opposite angle. Therefore we use the Sine Rule. e.g. 2:
