This worksheet is designed to replace a lecture on using the inverse trigonometric functions in right triangles. I include a trigonometric ratios chart (or SOH CAH TOA chart) with it, as I find it extremely helpful for students to have a separate chart to look up angles. I run the fourth page of this worksheet off as a separate handout and print it on a colorful sheet of paper for them so they can easily find it.
I start out class with a 15-minute "mini-lesson," giving my students some basic examples of what today's lesson will be about: for instance, I show them how to find one acute angle of a right triangle in which the hypotenuse is 12 and the adjacent leg is 7. 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 worksheet named 'Inverse Trigonometric Functions Spring 2014' (http://www.teacherspayteachers.com/Product/Inverse-Trigonometric-Functions-Spring-2014-includes-Trigonometry-Ratios-Chart-1267650
), and immediately after this worksheet, I use the worksheet named 'Law of Cosines Solving for Sides Spring 2014' (http://www.teacherspayteachers.com/Product/Law-of-Cosines-Solving-for-Sides-Spring-2014-1267672
