This is a unit circle I created for students to keep as a reference. It has the special right triangles that can be rotated around the circle. I have guided notes that go along with this (listed separately). We spent two days putting this unit circle together as an interactive lesson.
A helpful tool for students. This is a reference sheet that students can use to solve right triangle problems. Includes trig, Pythagorean Theorem, similar right triangles, and special right triangles.
