    About Triangle Calculations

    Triangles are fundamental geometric shapes with three sides and three angles. Understanding their properties is essential in geometry, trigonometry, and various practical applications.

    Triangle Types

    • By Sides: Equilateral (all equal), Isosceles (two equal), Scalene (all different)
    • By Angles: Right (90°), Acute (all < 90°), Obtuse (one > 90°)

    Formulas Used

    • Area (Base-Height): A = (1/2) × base × height
    • Area (Heron's Formula): A = √[s(s-a)(s-b)(s-c)], where s = (a+b+c)/2
    • Law of Cosines: c² = a² + b² - 2ab cos(C)
    • Perimeter: P = a + b + c

    Applications

    • Construction and architecture
    • Navigation and surveying
    • Engineering design calculations
    • Computer graphics and game development
