Reference Angles Foldable
I created this reference angles foldable for my trigonometry students to glue in their interactive notebooks.
The first image I gave students as a reference was from TutorVista.com. The second image I gave my students was from RegentsPrep.org.
On the inside of this booklet foldable, I had students sketch the angles (given in both degrees and radians!) and find the reference angle. I am happy to report that my students did not ask to convert the radians to degrees!!! I wrote more about my approach to teaching students to sketch angles in radians here.
Once your students understand the concept of a reference angle, give them some practice with my Trig Reference Angles Activity called Odd One Out.
