This lesson we looked at how to find the area of a segment. You can read the notes for this in the image on this section of the website. We then started work on our final skills check, which covers length of arcs, area of sectors and area of segments.  See Mrs Halls for a printed copy. These documents, including the answer sheet, are also available on Workspace.

Today we looked at how to find the length of an arc (a section of the circumference). Read the notes from the board here, or on the workspace, then complete the questions on workspace. See Mrs Halls for a printed copy if you were absent from class and want one. 

There are two different measurements for angles - degrees and radians. This video will show you how to change between them and how to use both of them. 

Today we'll look at how to work out the area of Sector, a slice of a circle. Imagine a slice of pizza, this is the shape we will be working on. Watch the video here on the website or on the workspace. There will be a paper worksheet available from Mrs Halls, or you can access the questions to complete on Workspace. 

Now that we have completed our work on Area of Triangles, and the different versions of the Sine Rule and Cosine Rule we will complete a skills check to practice applying these to different types of questions. A copy of the skills check will be provided in class, or you can access an electronic version here on the website or on workspace. An answer sheet with solutions is available 

We're going to look at how to use the Cosine Rule for Angles. This will be provided on the formula sheet for the assessment, but you need to practice using it correctly. Watch the video here or on the workspace if you miss this lesson.  A paper copy of the worksheet will be available from Mrs Halls, or you can complete the using the workspace. 

We're going to look at how to use the Cosine Rule for Sides. This will be provided on the formula sheet for the assessment, but you need to practice using it correctly. Watch the video here or on the workspace if you miss this lesson.  A paper copy of the worksheet will be available from Mrs Halls, or you can complete the using the workspace. 

We're going to look at how to use the Sine Rule for Angles. This will be provided on the formula sheet for the assessment, but you need to practice using it correctly.

We're going to look at how to use the Area of Non Right Angled Triangles. This will be provided on the formula sheet for the assessment, but you need to practice using it correctly. Watch the video here or on the workspace if you miss this lesson.  A paper copy of the worksheet will be available from Mrs Halls, or you can complete the using the workspace.
