Abstract
With what relief a student uses the simple formula ‘Area of a triangle = 1/2 base × height’! Though Heron’s formula for the area in terms of its three sides has a pleasing symmetry convenient for memorization, it often seems cumbersome in comparison. A look at how this formula is derived will perhaps enable the student to remember and appreciate the formula, not for this reason but for the sheer elegance of the derivation.
