WitrynaHeron’s formula allows us to find the area of a triangle when only the lengths of the three sides are given. His formula states: K = s(s − a)(s −b)(s − c) Where a, b, and c, … Heron's formula can be obtained from Brahmagupta's formula or Bretschneider's formula by setting one of the sides of the quadrilateral to zero. Brahmagupta's formula gives the area K of a cyclic quadrilateral whose sides have lengths a, b, c, d as. where s, the semiperimeter, is defined to be. Zobacz więcej 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, 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 historian Thomas Heath suggested that 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 lengths of the sides so that a ≥ b ≥ c and computing Zobacz więcej Let △ABC be the triangle with sides a = 4, b = 13 and c = 15. This triangle’s semiperimeter is 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 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 Heron's formula is a special case of Brahmagupta's formula for the area of a cyclic quadrilateral. Heron's formula and Brahmagupta's formula are both special cases of Zobacz więcej

The first step is to find the semi perimeter of a triangle by adding all three sides of a triangle and dividing it by 2. The next step is to apply the semi-perimeter of triangle value in the main formula called “Heron’s Formula” to find the area of a triangle.
