We are going to consider:

1.) Basic angle properties and angles in a triangle;

2.) Alternate and corresponding angles;

3.) Interior & exterior angles in polygons;

4.) Circle Therory

• Symmetry Properties of Circles;
• Basic Circle Theory;
• Further Circle Theory;
• Angles in Circles (combined).

5.) Line & rotational symmetry.

Below are some related extension questions in case you have extra time after finishing the work above. The answers to these questions are at the bottom of section 4 (line & rotational symmetry) (in a separate place so they don’t distract you whilst you are working on the questions)
