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.
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).

Questions to do with angles. These are GCSE type questions, mainly from foundation papers.
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.
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.
A video showing students how to answer questions on angles.
Questions about angles on a straight line.
Interior and exterior angles and how to find them and then how to use this information to find the answers to slightly more complex problems.
Use the information you know to find the information you don't in terms of angles.
Find the size of various angles giving reasons
There are various angles to measure and then several angles to draw. This is good to use in conjunction with the angles video below.
