What are the common mistakes in The angle at the centre?

When a pupil makes one of these on Revision Workshop, the marking engine names the mistake and explains it, instead of just marking the answer wrong.

• Confuses the angle at the centre with the angle at the circumference of a circle

  Assumed the angle at the centre equals the angle at the circumference, instead of doubling the circumference angle

• Verifies the result for a single drawn diagram rather than proving it in general

  Only checked the relationship for one specific diagram or set of angle values, rather than proving the doubling relationship holds in general using the exterior angle argument

• Uses only one base angle instead of both when solving an isosceles triangle problem

  Subtracted only one base angle from 180° instead of recognising the triangle is isosceles with TWO equal base angles to subtract when finding angle TOA
