In geometry, Heron's formula (or Hero's formula) gives the area of a triangle in terms of the three side lengths a, b, c. If $${\textstyle s={\tfrac {1}{2}}(a+b+c)}$$ is the semiperimeter of the triangle, the area A is, $${\displaystyle A={\sqrt {s(s-a)(s-b)(s-c)}}.}$$It is named after first-century … Zobacz więcej Let △ABC be the triangle with sides a = 4, b = 13 and c = 15. This triangle’s semiperimeter is $${\displaystyle s={\frac {a+b+c}{2}}={\frac {4+13+15}{2}}=16}$$ and so the area is Zobacz więcej There are many ways to prove Heron's formula, for example using trigonometry as below, or the incenter and one excircle of the triangle, or as a special case of De Gua's theorem (for the particular case of acute triangles), or as a special case of Trigonometric … Zobacz więcej • Shoelace formula Zobacz więcej Heron's formula can also be written in terms of just the side lengths instead of using the semiperimeter, in several ways, Zobacz więcej The formula is credited to Heron (or Hero) of Alexandria (fl. 60 AD), and a proof can be found in his book Metrica. Mathematical … Zobacz więcej Heron's formula as given above is numerically unstable for triangles with a very small angle when using floating-point arithmetic. A stable alternative involves arranging the … Zobacz więcej Heron's formula is a special case of Brahmagupta's formula for the area of a cyclic quadrilateral.
