WebIn our text, Precalculus (fifth edition) by Michael Sullivan, a proof of Heron™s Formula was presented. This proof invoked the Law of Cosines and the two half-angle formulas for sin … WebIt is interesting to note that Heron's formula is an easy consequence of Brahmagupta's. To see that suffice it to let one of the sides of the quadrilateral vanish. On the other hand, Heron's formula serves an essential ingredient of the proof of Brahmagupta's formula found in the classic text by Roger Johnson. Proof

In general, it is a good advice not to use Heron's formula in computer programs whenever we can avoid it. For example, whenever vertex coordinates are known, vector product is a much better alternative. Main reasons: http://math.fau.edu/yiu/Southern080216.pdf
WebSep 14, 2024 · A very modest tribute to John Conway. Heron’s formula for the area of a triangle in terms of the lengths of its sides is certainly one of the most beautiful algebrogeometric results of ancient mathematics. Its original (supposed) proof by pure geometry is rather convoluted [ 5, pp. 321–323], as is Euclid’s proof of the Pythagorean … WebHeron’s formula is a formula to calculate the area of triangles, given the three sides of the triangle. This formula is also used to find the area of the quadrilateral, by dividing the quadrilateral into two triangles, along its …
