Students will practice finding the exact value of a trigonometric function by using the Sum and Difference of Angles Identities with this “Triples” Activity. Some angles are given in degrees and some are given in radians. Both positive and negative angle measures are included.
Students find the exact value for each of the 24 cards using the identities, then look for the matching “triples”. There will be 8 sets of three cards, each having the same answer. I recommend that students work in groups of 3-4 on this activity. They can show their work directly on the back of the card, or on a separate sheet of paper if you prefer. Once they are finished, I have my students staple their “triples” together and place in a zip-lock bag.
An answer key is included to ensure the correct cards are matched.
