              Trigonometry Introduction

              Students discover the three trigonometric ratios Sin, Cos and Tan through constructions.  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 identify the three trigonometric ratios of a right-angled triangle.
              • Most students should be able to calculate the Opposite and Adjacent side using Sin θor Cos θ
              • 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
