The Core Concept: Triangle Calculation
A Triangle Calculator is a versatile tool used to determine unknown geometric properties of a triangle, such as side lengths, interior angles, perimeter, and area. The required inputs depend on which properties are already known, and the calculation relies on fundamental geometric theorems and trigonometric laws.
The primary laws used for calculation are the Pythagorean Theorem (for right triangles), the Law of Sines, and the Law of Cosines (for all triangles).
1. Calculating the Area
The area of any triangle can be calculated if the length of the base (b) and the corresponding height (h) are known, or if two sides (a, b) and the angle between them (C) are known (using the Sine Rule for Area).
2. Right Triangle Calculations (Pythagorean Theorem)
For a right triangle (one angle equals 90 degrees), the lengths of the three sides (a, b, and hypotenuse c) are related by the Pythagorean Theorem, which simplifies many calculations.
Trigonometric functions (sine, cosine, tangent) are also used to find unknown angles or sides in a right triangle.
3. General Triangle Calculations (Law of Cosines)
The Law of Cosines is used when two sides and the included angle (SAS) are known, or when all three sides (SSS) are known, allowing the calculation of the third side or any angle.
4. General Triangle Calculations (Law of Sines)
The Law of Sines is used when two angles and any side (AAS or ASA) or two sides and a non-included angle (SSA) are known, linking the ratios of the side lengths to the sines of their opposite angles.
