Overview
Heron's Formula is a mathematical formula that helps us find the area of a triangle when we know the lengths of all three sides but don't know the height. This formula is particularly useful for scalene triangles where calculating height directly is difficult. Named after the ancient Greek mathemati
Key Concepts
Area of triangle = √[s(s
Area of triangle = √[s(s-a)(s-b)(s-c)], where a, b, and c are the three sides of the triangle, and s is the semi-perimeter
Semi
Semi-perimeter is half the perimeter of the triangle, calculated as s = (a+b+c)/2, where a, b, c are the three sides
Heron's Formula works for all types
Heron's Formula works for all types of triangles - scalene, isosceles, equilateral, and right triangles
For right triangles
For right triangles, the area calculated using Heron's Formula can be verified using the standard formula (½ × base × height)
