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
