Tangent ratio is yet another trigonometric ratio for right-angled triangles. Tangent ratio is the ratio of opposite side to adjacent side of a right triangle. Same as the sine and cosine ratios, tangent ratios can be used to calculate the angles and sides of right angle triangles.

Basic concepts: Pythagorean theorem,

Related concepts: Unit circle,

- IntroductionWhat are sine, cosine and tangent?
- 1.Determine each tangent ratio using a calculator

i) $\tan 70^\circ$

ii) $\tan-134^\circ$ - 2.Determine the angle to the nearest degree using a a calculator

i) $\tan \theta = 0.64$

ii) $\tan \theta = -1.45$ - 3.Determine the angles and sides using Tangenta)Find angle A and B:

b)Find the value of "x" using tangent

c)Find the value of "x" using tangent

- 4.Draw and label a right triangle to illustrate tangent ratio, then calculate the angle.a)$\tan \theta = {5 \over 9}$
