Webb8 sep. 2016 · Heron’s theorem – or sometimes Hero’s theorem – gives the area of any triangle in terms of the lengths a, b and c of its three sides. The more well-known formula gives the area as half the product of the base c and height h, that is. A = ½ c h But in many practical contexts the perpendicular height h is not known, whereas the lengths of the …

WebbProof of Heron’s formula An elementary algebraic proof of Heron’s formula is rather sophisticated and is difficult for students to do without help. The following proof was done individually with CAS and the following worksheet. Follow the instructions. a) We calculate the square of Heron’s formula area 2 = heron(a,b,c)2 in order to avoid ... WebbIt 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.
