The three formulas for the area of a triangle are: 1) Base x Height / 2: Most common method. 2) Heron's Formula: √[s(s-a)(s-b)(s-c)], with s = (a+b+c)/2. 3) Trigonometric Formula: (1/2)ab*sin(C), useful for non-right triangles using two sides and included angle.
FAQs & Answers
- What is the most common method to calculate the area of a triangle? The most common method is to use the formula: Area = (Base x Height) / 2.
- How do you apply Heron's formula? To use Heron's formula, first find the semi-perimeter s, then apply the formula Area = √[s(s-a)(s-b)(s-c)].
- When should the trigonometric formula be used? The trigonometric formula is useful for non-right triangles when you have two sides and the included angle: Area = (1/2)ab*sin(C).
- Can these formulas be used for any triangle? Yes, these formulas can be applied to calculate the area of any triangle, regardless of its type.
