Semi perimeter of a triangle formula
The semiperimeter is used most often for triangles; the formula for the semiperimeter of a triangle with side lengths a, b, c In any triangle, any vertex and the point where the opposite excircle touches the triangle partition the triangle's perimeter into two equal lengths, thus creating two paths each of which has a length equal to the semiperimeter. If A, B, B', C' … WebFeb 20, 2024 · The area of the triangle is equal to the product of the inradius and half the sum of all the sides. So the formula is A = r (a+b+c)/2. Half of the sum of all sides is also called the semi-perimeter,s.
