Students learn how to calculate unknown lengths and angles in right-angled triangles using Sin, Cos and Tan.
Later, 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 triangles using trigonometrical relationships.
