# Angles

Angle is a measure of the amount of turn in the same way as a length is the measure of the amount of distance.

At GCSE, we measure angles in degrees. There are two sub-units to a degree. There are 60 minutes in one degree and there are 60 seconds in one minute.

In a complete turn, there are 360 degrees. There are also 21,600 minutes in a complete turn and 1,296,000 seconds in a complete turn.

At A level and beyond, you will measure angles in radians. There are 2 PI radians in a complete turn (or circle).

## Parallel Lines and Angles

Finding angles using parallel lines and alternate angles. Provides a format to encourage the students to give reasons for their answers.

## GCSE type questions about angles

Questions to do with angles. These are GCSE type questions, mainly from foundation papers.

## PowerPoint about angles in triangles

PowerPoint about angles and showing how to set out the answers in a logical format so that they make sense.

Problems about angles which give the students the opportunity to fine the missing angles in a range of questions.

A PowerPoint presentation introducing students to corresponding and alternate angles.

## Angles Matching Game

Cut up each card and then match up each angle with its corresponding name. This is a sorting activity which provides the students with a different way of learning about angles.

## Angle Problems Video
