Reflection: Intervention and Extension Trigonometric Ratios - Section 3: Activity


It is helpful for the students to set up the ratio in triangles as shown in the picture. I instruct the students to cover letter representing the missing information. Then they multiply or divide depending on the given information. This method helps students who still have difficulty solving algebraic equations.
