Geometry is concerned with the various aspects of size, shape and space. In this free course you will explore the concepts of angles, shapes, symmetry, area and volume through interactive activities.

After studying this course, you should be able to:

  • understand geometrical terminology for angles, triangles, quadrilaterals and circles
  • measure angles using a protractor
  • use geometrical results to determine unknown angles
  • recognise line and rotational symmetries
  • find the areas of triangles, quadrilaterals and circles and shapes based on these.

This course looks at various aspects of shape and space. It uses a lot of mathematical vocabulary, so you should make sure that you are clear about the precise meaning of words such as circumference, parallel, similar and cross-section. You may find it helpful to note down the meaning of each new word, perhaps illustrating it with a diagram.

This module contains some interactive geometry activities which use the Java based software, Geogebra. You will need to install Java on your computer in order to use the activities. Java can be obtained free [Tip: hold Ctrl and click a link to open it in a new tab. (Hide tip)] . Further information on Geogebra is available on Geogebra .

If you are unable to use this software, you will still be able to complete this module.

If you have Java installed, you should be able to follow the link to the first activity below. This activity explains how to use some of the tools you will need in the rest of the module.
