Geometry Chapter 8.  We are familiar with the Pythagorean Theorem:

Trigonometry can be used for two things: 1.Using 1 side and 1 angle to work out another side, or 2.Using 2 sides to work out an angle.

Use Pythagorean Theorem: x = = 12.7 rounded This is a Triangle: ON A SHEET OF PAPER.

Opener. The Trigonometric Functions we will be looking at SINE COSINE TANGENT.

The Trigonometric Functions SINE COSINE TANGENT. SINE Pronounced “sign”

Trigonometric Ratios Section 8.1. Warm Up State the following: 1.Angle opposite AB 2.Side opposite angle A 3.Side opposite angle B 4.Angle opposite AC.

Adjacent = Cos o x H Cosine Ratio To find an adjacent side we need 1 side (hypotenuse) and the included angle. a = Cos ° x H a = Cos 60° x 9 a = 0.5 x.

Ratios for Right Angle Triangles.  Sine = opposite hypotenuse  Cosine = opposite hypotenuse  Tangent = opposite adjacent Sin = OCos = ATan = O H H.
