  4. A B C Chapter 5 Trigonometry • Consider DABC • Label the sides as hypotenuse (hyp), opposite (opp), and adjacent (adj) for angle A

  5. Label the sides as hypotenuse (hyp), opposite (opp), and adjacent (adj) for angle B • Note: The opposite and adjacent switches places when switching angles. • The hypotenuse does not switch. It is always across from the right angle. A C B

  6. Trig Functions • sin = • cos = • tan = SOHCAHTOA Some Old Hippie Caught Another Hippie Trippin’ On Acid

  7. A B C • Write the trig ratios for angle A sin A= cos A = tan A = 5 3 4
