Right Triangles (Trig Ratios)-Group Activity/Practice Forms A,B,C&D

This trigonometry activity consists of a total of 24 problems in which students will practice finding missing side and angle measures in right triangles using the sine, cosine, and tangent ratios. The problems are divided into six sections of four similar problems.

The product is intended to be used for groups of maximum four members (there is a problem for each partner of the group in a section) . Solving similar problems in each section encourages the partners to help each other with methods. Moreover, this group activity may easily turn into a competition between groups.

The product can be also used as an independent practice with four similar forms (form A, form B and forms C and D) if preferred. I have included a modified worksheet so the product can be used in this way.

Here is the description of the problems in each section:

Section 1&2 – given the hypotenuse and an acute angle. Section 3 – given an acute angle and its opposite side. Section 4 – given an acute angle and its adjacent side. Section 5 – given a leg and the hypotenuse. Section 6 – given the two legs. Students have to find the missing sides or/and angles.

Answer keys are included.
