Proof of heron formula
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 Brahmagupta's formula (for the case of a degenerate cyclic quadrilateral).

WebUsing Heron’s Formula. When the lengths of the three sides of the triangle are known, Heron’s formula is used to find the area of a triangle. Alt tags: An equilateral triangle with sides “a” units. Consider a triangle ABC with sides a, b, and c. The Heron’s formula to find the area of the triangle is given by WebApr 8, 2024 · Heron's Area Formula Let a, b, and c be sides of AABC. Let s equal the "semi-perimeter" of AABC a+b+c 2 8 = The area of AABC is A = √√s (s – a) (s – b) (s — c) Your friend just bought a triangular plot of land to open a dog daycare center. The lengths of each side of the triangle plot of land is 225 ft, 900 ft, and 850 ft.
