Did you know there are a number of parts that make up a circle?
You can see these parts below:
There is another part of circles that is not listed above. It is called a secant. A secant is basically a line that intersects a circle at two points. This is illustrated below:
See if you can use the above diagram to label the parts of the following circles. We will do some in class first before you can have a go yourself! :)
You can also use this maths dictionary here if it helps too! If you want to get really crazy you should check out this resource here. It gives you more information than you could almost want to know about circle definitions and theorems (though the first page is still very useful to us!) :)
