Rt triangle trig
- 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:
