Transcript

  • 1. Right Triangle Trigonometry
  • 2. A right triangle has:
    • one right angle and 2 acute angles
  • 3. Basics of Right Triangle Trig
  • 4.
    • In mathematics, we often use Greek letters to label angles.
    • In this example, the Greek letters “alpha” and “beta” are used.
    • By the end of today’s
    • lesson, you will be able
    • to find the mistake in this
    • picture!
  • 5. Theta
    • Along with alpha and beta, the Greek letter theta is used to denote the angle in question.
    • Theta looks like a 0 with a line through the center, 
  • 6. Mnemonic to Memorize
    • We use SOH-CAH-TOA to help us to remember the basic trigonometric ratios:
  • 7.
    • Below you can see part of its usefulness!
  • 8. Real Life Examples
    • Right triangle trigonometry is useful to help solve real life problems.
    • The following are all examples of real life problems.
  • 9.  
  • 10. We can use trigonometry to find out the height of the kite!
  • 11.  
  • 12.  
  • 13. Oceanography
  • 14. Angle of Elevation
    • Angle of Elevation is used in many real life right triangle trigonometry problems.
  • 15. Calculator
    • We can use our calculators to help solve trigonometry problems
