I used this lesson for an observation, I had to introduce Trigonometry but decided to use special angles to introduce it so that they weren't an after thought.
We used the "special" triangles to derive the relationships, and once they understood the relationships without using calculators, then we were able to go on to use calculators and any angle.
Hopefully it will help them to remember how to find the special angles a bit better! Could be developed further by using the special angles for more q's to rearrange before using other angles.
Please review :)
