Discovering (or Rediscovering) Trig Ratios

I know it will be tempting to use your calculator here. But please do not!

Naming Trig Ratios

Complete a selection of the following problems from Haese & Harris MYP Math 5 (Standard). These will help you to solidify your usage of Trig Ratios. But remember that it is much more important that you understand how trig ratios work and their underlying concepts. The questions for practice here are relatively low level. If your understanding of the concepts is weak you will struggle when you see questions that are slightly unfamiliar.
