# 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 additionalÂ theorems associated with 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 functions to calculate angles in right-angled triangles.
• Some students should be able to calculate an angle in an isosceles triangle using Trigonometrical functions.
