  4. Apr 8, 2024 · Understand the equation you will use to solve this equation. You will use the equation K=bh/2 . K is the area of the triangle while b is the base and h is the height of the triangle.

  5. The area of a scalene triangle can be calculated using Heron's formula, Area of triangle = [s(s−a)(s−b)(s−c)], when all the three side lengths are given. Here, a, b and c are the 3 different sides of the scalene triangle, and 's' is the semi perimeter of the triangle.

  6. The sum of all internal angles of a triangle is equal to 180°. The length of the side of a triangle corresponds to the size of the angle opposite the side; the longer the side, the larger the angle. It is worth noting that the ratios do not correspond: if side a is twice the length of b, it does not mean that angle A is twice the size of angle B.
