# Trigonometry Finding Lengths in Right-Angled Triangles

Students learn how to calculate unknown lengths 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 the length of a right-angled triangle using the Sine and Cosine functions.
• Most students should be able to calculate the length of a right-angled triangle using the Sine, Cosine and Tangent functions.
• Some students should be able to calculate the length of a polygon edge by considering its right-angled triangular components.
