Trigonometry Review
Trigonometry is a set of tools that
help determine the measures of a
right triangle (sides and angles).
We are going to look at 3 of the
Trig Tools: Sine, Cosine, and
Tangent.

March 19 Trig Review

  1. 1. Trigonometry Review
  2. 2. Trigonometry is a set of tools that help determine the measures of a right triangle (sides and angles).
  3. 3. We are going to look at 3 of the Trig Tools: Sine, Cosine, and Tangent.
  4. 4. B hyp ote n use C A sine deals with an angles relationship with the opposite side and the hypotenuse. sinA = O/H sinB = O/H
  5. 5. B hyp ote n use C A Cosine deals with an angles relationship with the adjacent side and the hypotenuse. cosA = A/H cosB = A/H
  6. 6. B hyp ote n use C A Tangent deals with an angles relationship with the opposite side and the adjacent side. tanA = O/A tanB = O/A
  7. 7. B c 8 48° A C b A = 48° a=8 B=? b=? C=? c=?
  8. 8. B c 8 48° A C b
  9. 9. B 8 48° A C b
  10. 10. B 8 48° A C
  11. 11. B c 8 48° A C b A = 48° a=8 B=? b=? C=? c=?
