This is the area of a quadrilateral with sides a,b,c,d inscribed in a circle, i.e., a cyclic quadrilateral. Naturally every triangle is cyclic, meaning that it can be inscribed in a circle, and a triangle can be regarded as a quadrilateral with one of its four edge lengths set equal to zero.

• Build your own rvwe see an informal proof of the fact that a tangent to a circle is perpendicular to a radius drawn to the point of tangency. Two right triangles are congruent if their hypotenuses and one pair of legs are congruent, a theorem that will be used to prove that tangent segments drawn from an external point to a circle are congruent.
