The following task cards will review the basics of finding trigonometric ratios using SOH-CAH-TOA. Students will find trig ratios after using the Pythagorean Theorem, 30-60-90, and 45-45-90 skills. The "Challenge" cards require students to apply the trig ratios to problems beyond basic triangles. There are 4 sets of task cards - the problem is on the front and the answer keys are on the back.
