FAQ: This App does not work properly it keeps on crashing, why?
Sometimes Apps just do not download properly. You will need to download it again, for free, using itunes. See Apple Support Pages
About half way down the page there's a set of instructions that starts 'Reinstall the affected application'. Once iTunes has it then you sync your device and it should then work. If it does not then please to contact me.

When the Application Starts

The main page shows you a list of the topics that are covered in this App.

Select the blue disclosure icon to the right to reveal the information about that topic.

The more complicated the subject matter the further down the list the topic is. The topics at the top are the fundamentals that need to be understood so that later topics make sense.

Topic - Diameter

One of the simpler topics about a circle. At the top is a diagram illustrating the topic and below it is a scrollable area explaining the topic.

Topic - Segment

A more complicated topic explaining about segments of a circle. Once again there is a diagram and then text below it to explain the topic.
