Trigonometry
Sin, cos and tan relate an angle and two sides in a right-angled triangle.
Formula triangles
Formula triangles
- Formula triangles can be used to remember the ratios (SOHCAHTOA) and to rearrange the ratios so they can be used.
- The side opposite the angle being used is referred to as the ‘opposite’ and the side next to the angle being used is called the ‘adjacent’.
