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?

## Go Maths

Learning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths page is an alphabetical list of free activities designed for students in Secondary/High school.

## Description of Levels

Close

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:

Answers to this exercise are available lower down this page when you are logged in to your Transum account. If you don’t yet have a Transum subscription one can be very quickly set up if you are a teacher, tutor or parent.

## Information

### Angles at a point

The sum of the angles that fit around a point is 360°.

a° + b° + c° = 360°

### Angles on a straight line

The sum of the angles that fit on a straight line 180°.

a° + b° = 180°

### Vertically opposite angles

Where two straight lines cross vertically opposite angles are equal.

a = b
