Students learn how to derive and apply the Sine rule to find missing angle in triangular shapes.

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

**Differentiated Learning Objectives**

- All students should be able to identify the hypotenuse of a right angled triangle as the longest side.
- Most students should be able to calculate length of the hypotenuse in a right angled triangle.
- Some students should be able to calculate the length of the hypotenuse in an isosceles triangle when given its base and perpendicular height.
