I assign Last Practices the night before a quiz so students have something to "study." I then email them the answers so they can check their work and I answers questions the next day before the quiz. This right triangle trig last practice has all 6 trig functions, finding angles, solving triangles and using the calculator to evaluate trig functions for non-special angles.
This is a practice worksheet after teaching the special triangle patterns (30-60-90 & 45-45-90). I like to use different measurements to help students learn that radicals are just numbers and a special triangle pattern may be there even if it doesn't look like it.
