It can be used to derive Heron's formula, when written in its extended form, achieved by tacking on "=2R" to the end of the original statement.
It can be used to derive Heron's formula, when written in its extended form, achieved by tacking on "=2R" to the end of the original statement. It is useful when two angles and a side of a triangle are known, but can give an ambiguous result when two sides and the non-included angle are given, in which case it is unclear whether the triangle is acute or obtuse. For ten points, identify this law from geometry that states that, for all triangles, the ratio of each side length to the sine of the angle opposite its constant.
