I got shown this by a colleague so thought I would PowerPoint it; there are essentially a few versions of the same thing:

  1. Minimally labelled etc - for a strong set of mathematicians
  2. All angles marked
  3. The side or angle you need to find next is highlighted

I will use this to introduce the addition formulae. There may well be other/better versions out there so I am sorry if I have wasted your time.
