This worksheet is designed to replace a lecture on right triangle trigonometry, which some call "SOH CAH TOA." It is a three-page worksheet, but the fourth page is a trigonometric ratios chart, which I recommend you photocopy on a separate, colorful sheet of paper for each student, as it comes in handy when they are both looking up trigonometric ratios, as well as when they are trying to do inverse trigonometric functions.

I start out class with a 15-minute "mini-lesson," giving my students some basic examples of what today's lesson will be about. Once the mini-lesson is over, I have them get to work within their groups on this worksheet.

I use this activity within cooperative groups, and I circulate to make sure they are getting the purpose of the questions.

The file includes spiral review problems.

This worksheet is intended to be written on directly.

Please download the pdf preview file first, so you can see exactly what's included; the product file is a word document, which you may personalize for your students.

Immediately before this worksheet, I use the mini lesson named 'Introduction to Trigonometry Worksheet Spring 2014 mini lesson' (http://www.teacherspayteachers.com/Product/Introduction-to-Trigonometry-Worksheet-Spring-2014-mini-lesson-1267154), and immediately after this worksheet, I use the worksheet named 'Inverse Trigonometric Functions Spring 2014' (http://www.teacherspayteachers.com/Product/Inverse-Trigonometric-Functions-Spring-2014-includes-Trigonometry-Ratios-Chart-1267650)
