Heron's Formula Mastery

A = (s(s+a)(s+b)(s+c)), where s is the semi-perimeter and a, b, c are the sides of the triangle

A = √(s(s-a)(s-b)(s-c)), where s is the semi-perimeter and a, b, c are the sides of the triangle (correct)

A = (s(s-a)(s-b)(s-c)), where s is the semi-perimeter and a, b, c are the sides of the triangle

A = √(s(s+a)(s+b)(s+c)), where s is the semi-perimeter and a, b, c are the sides of the triangle

Semi-perimeter of the triangle (correct)

Sum of the three sides of the triangle

Product of the three sides of the triangle

Square of the semi-perimeter of the triangle

Only isosceles triangles

Any triangle (correct)

Only equilateral triangles

Only right-angled triangles
