Worksheet 2:8 introduces the trig ratios of sine, cosine, and tangent. To review the ratios, consider a triangle ABC with angle ˚ as marked. b c a ˚ A C B The hypotenuse (hyp) of the triangle is c; the adjacent (adj) side is b; the opposite (opp) side is a. The side of length a is opposite the angle, and the side of length b is the side ...
