Students learn how to calculate unknown lengths and angles in right-angled triangles using Sin, Cos and Tan.  As learning progresses they are challenged to apply other facts about triangles to solve more complex problems.

Differentiated Learning Objectives

• All students should be able to calculate an angle in a right angled triangle using trigonometrical relationships.
• Most students should be able to calculate a combination of angle and length in a right angled triangle using trigonometrical relationships.
• Some students should be able to demonstrate geometrical relationships in right angled triangle using trigonometrical relationships.
