A triangle is a three-sided polygon with three edges and three vertices. The properties of a triangle, such as its area, perimeter, and type, can be calculated based on the lengths of its sides.
Key Concepts
Perimeter: The sum of the lengths of the three sides.
Area: Calculated using Heron’s Formula.
Type: Determined by the lengths of the sides (Equilateral, Isosceles, or Scalene).
