Hi everyone, I am trying to learn how to understand the unit circle and a few different concepts for an upcoming quiz. I went on geogabra and created a circle with a center and radius. Within the circle I created a right triangle and made sure it is 90 degrees. I also got the distance of the angles. I uploaded a picture.
