Understanding Right Triangles

Key Properties

  • One angle is always 90°
  • Other angles sum to 90°
  • Follows Pythagorean theorem
  • Area = (base × height) ÷ 2
  • Perimeter = sum of all sides

Trigonometric Ratios

  • sin(θ) = opposite / hypotenuse
  • cos(θ) = adjacent / hypotenuse
  • tan(θ) = opposite / adjacent
  • θ represents any acute angle
  • Ratios help find missing sides

Applications

  • Construction and architecture
  • Navigation and surveying
  • Engineering calculations
  • Physics problems
  • Height and distance measurement
