Right Triangle Trigonometry
A right triangle has:
• one right angle and 2 acute angles
Basics of Right Triangle Trig
• 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!
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,
Mnemonic to Memorize
• We use SOH-CAH-TOA to help us to remember the basic trigonometric ratios:
• Below you can see part of its usefulness!
Real Life Examples
• Right triangle trigonometry is useful to help solve real life problems.
• The following are all examples of real life problems.
We can use trigonometry to find out the height of the kite!
Oceanography
Angle of Elevation
• Angle of Elevation is used in many real life right triangle trigonometry problems.
Calculator
• We can use our calculators to help solve trigonometry problems
