Trigonometry

1. Overview

   • The Hypotenuse is the longest side of any right angled triangle
   • The side opposite a given angle is called the opposite side
   • The side next to (or adjacent to) a given angle is called the adjacent side

2. The Trigonometric Ratios

   • SineA= opposite divided by the Hypotenuse
   • Cosine A= Adjacent divided by the Hypotenuse
   • Tangent A= Opposite divided by the Adjacent

3. SOHCAHTOA

   • SOH= Sine, Opposite, Hypotenuse
   • CAH= Cosine, Adjacent, Hypotenuse
   • TOA= Tangent, Opposite, Hypotenuse
