In this lesson we shall cover

- What are Radians?
- Converting between degrees and radians
- Arc Length
- Sector Area
- Area of Triangle
- Area of Segment

Here we introduce the a new measure of angle size, Radians. We look at where we use radians and why it helps us.

We need to be able to convert between radians and degrees easily. We will construct a formula to allow us to easily convert between both of these

Initially we will look at the GCSE formula for finding the Arc length. We then look at how much easier the A-Level formula is for working our arc length
