This is a practice activity designed to allow students to gain confidence in working with trig ratios. The problem set is divided into four 'tasks', each of which has a specific focus.
Task 1 - Writing Trig Ratios Given a Triangle
Task 2 - Understanding the Relationships Between Sine, Cosine, & Tangent of Complementary Angles
Task 3 - Using a Given Trig Ratio to Draw and Label a Triangle and Determine the Length of the Missing Side
Task 4 - Understanding the Relationship Between the Trig Ratios of Corresponding Angles in Similar Triangles
Upon completion of each 'task' students are to check their answers. In tasks 1 & 2, correct answers for the questions at the beginning of the set allows students to skip specific questions and move on to more challenging work. Incorrect answers require students to complete the remaining questions for additional practice.
This activity can be set up to allow students to check their own work or have their work checked by the teacher at specific points. This allows for quick feedback for students and eliminated the need for the practice work to be graded at the end of the class period. A detailed answer key is included with this file.
This is intended to be a practice activity for use after students have been introduced to the indicated concepts. The practice set is editable, allowing teachers to add their own questions or to edit and reformat the existing questions.
