Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician?

Level 1  Angles at a point
Level 2  Angles on a straight line
Level 3  Vertically opposite angles
Level 4  Mixed questions
The mixed questions provide a recap of levels one to three and introduce some algebra. This level offers an opportunity for a little more problem solving rather than simply applying a rule.
Example:
Angles at a pointThe sum of the angles that fit around a point is 360°. a° + b° + c° = 360° 

Angles on a straight lineThe sum of the angles that fit on a straight line 180°. a° + b° = 180° 

Vertically opposite anglesWhere two straight lines cross vertically opposite angles are equal. a = b
