Triangles are three-sided polygons, and they have various properties and formulas related to their sides, angles, and area.

Here are some important triangle formulas:

**Perimeter of a Triangle**: The perimeter of a triangle is the sum of the lengths of its three sides. Perimeter = Side1 + Side2 + Side3**Area of a Triangle**: The area of a triangle can be calculated using different formulas based on the available information:- a. If you know the base (b) and the height (h) of the triangle: Area = (1/2) * base * height
- b. If you know the lengths of all three sides (a, b, c) using Heron’s formula: Semi-perimeter (s) = (a + b + c) / 2 Area = √(s * (s – a) * (s – b) * (s – c))
