Heron's formula
Sign in to saveformula for calculating the area of a triangle
AI overview
Heron's formula is a mathematical method for calculating the area of a triangle using only the lengths of its three sides, without needing to know the height. This formula is useful because it allows you to find a triangle's area whenever you know all three side lengths, which is often simpler than measuring the height directly.
