WebHeron's Formula: For a triangle ABC with sides a, b, and c, let s = 1 2 ( a + b + c) (i.e. 2 s = a+b+ c is the perimeter of the triangle). Then the area K of the triangle is A r e a = K = s ( s − a) ( s − b) ( s − c). ( 7) To prove this, first remember that … WebA triangle is a polygon with three sides and three angles. The three sides for triangle ABC shown above, written symbolically as ABC, are line segments AB, BC, and AC. A vertex is formed when two sides of a triangle intersect. ABC has vertices at A, B, and C. An interior angle is formed at each vertex. incarnation\\u0027s td
