Now, a new article not only proves that theorem—which relies on the Law of Sines—but puts forth four more trigonometric proofs, as well as five additional proofs outside of trigonometry.

The adjacent side (\(a\)) is next to the angle in question (\(x\)). The trigonometric ratios for the angles 30°, 45° and 60° can be calculated using two special triangles. An equilateral ...
