GCSE Maths Speed Revision

Key facts for your Geometry and Measures syllabus revision

In order to survive your GCSE Mathematics examinations, it is important that you understand some of the key terms that you will come across throughout a whole variety of different questions. In order to give you a helping hand, we have created a song which summarises all the main terms, helping you remember the key facts for answering and solving those mathematical puzzles.

Some terms are obvious, and are not difficult to understand. Others are a little more tricky so it is important that we know their definitions:

• A line - has no curves

• Vertice/vertex (plural) - the point where two lines meet (think of a corner!)

• Edge - a line segment that joins 2 vertices

• Plane - a flat surface with no thickness

• Parallel lines - don’t intersect and are the same distance apart

• Right angles - an angle of 90 degrees or one quarter of a full revolution

To get these terms stuck in your headache, have a listen to our song and be sure that you are ready to face the upcoming examinations. Also take a look at some of our other songs which will give you more information on angles, and look at types other than the right angle - for example, acute, obtuse and reflex angles. There are loads of songs to pick from!
