Students discover the three trigonometric ratios Sin, Cos and Tan through constructions.

Later, as learning progresses, they are challenged to apply the three ratios to solve problems involving right-angled triangles.

**Differentiated Learning Objectives**

- All students should be able to identify the three trigonometric ratios of a right-angled triangle.
- Most students should be able to calculate the Opposite and Adjacent side using Sin Î¸or Cos Î¸
- Some students should be able to solve real-life problems involving the lengths of any side of a right-angled triangle using SOH CAH TOA
