This PowerPoint can be used as FLASH CARDS when run as a slide show. Designed to help students become fluent in the ratios for sine, cosine and tangent for the unit circle special angles. Currently slides are organized to practice sine and cosine values in mixed order followed by the slides for all of the tangent values in mixed order. All slides include a reference called "ask yourself..." designed to help students think visually of the triangles within the unit circle and horizontal or vertical legs, long, short or equal length legs in reference to 30, 45, & 60 degree angles. Tangent is explained as the slope of the radius and a review of dividing fractions as change in y over change in x reveals the tangent ratios.
