Trigonometry Duel - Unit Circle

An attempt at a trigonometry war card game. You take the role of the referee for two competing students. Each student is dealt a card with a trig ratio expression with a special angle from the unit circle. Your job is to determine which student has the expression with the higher value. The first student to 10 wins. Ties are a draw and no points are awarded. You may let students use a printed unit circle as a reference until they are ready to play from memory. Precalculus 12 T03.02 - Students should be able to determine, using a unit circle or reference triangle, the exact value of a trigonometric ratio for angles expressed in degrees that are multiples of 0°, 30°, 45°, 60°, or 90°, or for angles expressed in radians that are multiples of 0, π/6, π/4, π/3, or π/2 and explain the strategy.
