# Trigonometry – Angles in Right-Angled Triangles # Trigonometry – Angles in Right-Angled Triangles

Students learn how to apply Sin, Cos and Tan to find missing angles in right-angled triangles.

Later, as learning progresses they are challenged to apply additional theorems associated to triangles to solve more complex problems.

##### Differentiated Learning Objectives
• All students should be able to use the Sine and Cosine function to calculate angles in right-angled triangles.
• Most students should be able to use the Sine, Cosine and Tangent function to calculate angles in right angled triangles.
• Some students should be able to calculate an angle in an isosceles triangle using Trigonometrical functions.
