Partner Practice Activity for Trigonometry Topic Index | Algebra Index | Regents Exam Prep Center

The following worksheet is designed to be a "partner" activity for your classroom. 

This worksheet is a take-off on the Pair Share process.  I found that Pair Share with high school students is difficult to monitor.  In a true Pair Share, for each numbered question, each student is to wait for the other student to finish.  You guessed it -- teenagers wait for no one!   In this modified version, each student can work at their own pace.  The "partnership" only comes into play when the work is finished.  The answers to both columns in this activity are the same, but not in the same order.  Students must discuss and check to be sure that they have the same answers before handing in their papers.

Trig Twisters   Name______________________________ Name______________________________   Directions:  You and your partner will work together to solve these trigonometry related problems.  You solve the problems on the left and your partner will solve the problems on the right.  When you are done, your answers will match - but the answers are NOT in the same order in both columns.  Use your calculator and round answers to the nearest tenth, unless stated otherwise.  Good luck! 1.  Find:  5 times sin 90º 1.  What is the product of:      (-1)(cos 45º)(sin 45º) ?       2.  In right triangle ABC, with right angle at B, the sin A = 0.9.  Find A to the nearest degree.       2.  Find:  21 times tan 45º 3.  What is the product of:      5(sin 45º)(cos 45º) ? 3. Express sin A as a fraction:     4. Express cos B as a fraction.        4.  With right triangle DEF, with right angle at E, the tan D = 0.9.  Find D to the nearest degree. 5.  Which of the following is sin (45º)?      1)  0.5           2)  0.6      3)  0.7           4)  1.0       5.  Which of the following is cos (72º)?      1)  1.0             2)  0.8      3)  0.5             4)  0.3       6. Find x to the nearest integer.        6. Find CB.       7.  What is the value of  (-1)(cos 60º)? 7.   In this problem, x is: 1)  3.5 2)  5.4 3)  7.0 4)  7.9     8. In this problem, x to the nearest integer is: 1) 54 2) 72 3) 101 4) 112     8.  In right triangle ABC, tan A = 2.08.  Find A to the nearest degree. 9.  In right triangle ABC, sin A = .67. Find A to the nearest degree.       9.  What is the value of tan(68º) to the nearest tenth?
