WebThe height of a triangle can be found through the application of trigonometry.. Knowing SAS (side-angle-side) Using the labels in the image on the right, the altitude is h = a sin .Substituting this in the formula = derived above, the area of the triangle can be expressed as: = = = (where α is the interior angle at A, β is the interior angle at B, is the … WebAnswer by Ross Millikan is the best algorithm to solve this. Heron's formula gives you the area of a triangle from the length of the sides. Let the sides be a, b, c and s = a + b + c 2 then the area A = s ( s − a) ( s − b) ( s − c). Works in any dimension. Let M be the matrix with column vectors C − A and C − B.
