Episode 6 — Trigonometry

Trigonometric Ratios in Similar Triangles

Learners will be able to:

• Identify the trigonometric ratio that remains constant in similar triangles. • Explain why the size of a triangle makes no difference to the trigonometric ratios. • Compare and describe the effect of similarity on tangent ratios in different right-angle triangles. • Apply the concept of constant trigonometric ratios in similar triangles to solve problems involving right-angle triangles. • Interpret the implications of constant trigonometric ratios for solving side lengths and angle sizes in different right-angle triangles.
