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=?
