Law of Sines - A Plus Topper from c1.staticflickr.com

You use the law of cosines to relate the 3 sides of a triangle to one of the angles. If you want to find the obtuse angle, you have to subtract the acute angle from 180 or just use the law of sines on the smallest angle to ensure it works. According to the law, ⁡ = ⁡ = ⁡ =, where a, b, and c are the lengths of the sides of a triangle, and a, b, and c are the opposite angles (see the figure to the right), while r is the radius of the triangle's.

In order to use side c in the law of sines, we need to know angle c.

How do you do law of sines? In trigonometry, the law of sines relates the sides and angles of triangles. The sine law also works for obtuse triangles, as shown in the next instance. Note that the triangles aren't typically drawn to scale, meaning the angles and side measurements don't exactly.

To use the law of sines you need to know either two angles and one side of the triangle (aas or asa) or two sides and an angle opposite one of them (ssa).

Remember that if we can't solve it from what we have, and we have two of the three angles, we can obtain the third angle from geometry (the sum of angles in a triangle is 180°).

This law is extremely useful because it works for any triangle, not just a right triangle.
