Heron’s Formula Definition
Heron’s formula, states that “For a triangle having lengths, a, b, and c, and semi-perimeter of the triangle is ‘s’ the area of the triangle using Heron’s Formula” is discussed in the image above.
Heron’s Formula
Heron’s formula is a very popular formula for finding the area of a triangle when the three sides are given. This formula was given by “Heron” in his book “Metrica”. We can apply this formula to all types of triangles, be they right-angled, equilateral, or isosceles.
Heron’s formula, attributed to Heron of Alexandria around 62 CE, is used to calculate the area of a triangle based on the lengths of its sides. Expressed mathematically, if a, b, and c are the side lengths, then the area is given by: Area = A = √{s(s-a)(s-b)(s-c)} where s is the semi-perimeter of the triangle calculated as s = (a + b + c)/2
Let’s learn about Heron’s formula, definition of Heron’s Formula, Heron’s Formula expression, Heron’s Formula examples, and Heron’s Formula derivation in detail. We will also learn to apply Heron’s formula to different types of triangles.
