If you consider that every circle makes up 360 degrees (in terms of angles) from the center, then this comes easy. You need to divide the 360 degrees by 12, and you will be provided with 30 degrees. This means that every segment of the circle should consist of 30 degree angle segments. So all you need to do is use the protractor to give you the 30 degree angle, which will allow you to separate the separate parts of the circle.

You can't just do this by splitting the circle in half and then halving them until you finally reach the number of twelve. Not only will this involve a series of assumptions to even get to such a level of separation, but it will be generally messy and difficult to deal with. Using a ruler and a pencil simply won't do if you're looking at getting an accurate outline of a 12 part circle. Of course, if this is part of a mathematics question in academia then you're going to have to stick to the protractor method.

In an exam or during some kind of academic question you are being tested on your mathematical skills and your ability to use skills that have been taught to you to carry out tasks. Making an assumption and cutting up the circle with a ruler and a pencil does not demonstrate these skills and it does not demonstrate your mathematical ability. Instead it shows that you are unable to apply skills and that you do not take accuracy seriously within academia. This can be problematic and lose you marks in exams.

Stick to the method outlined that uses the protractor and of course the compass, and you will be sure that you will exceed in this area of mathematics and get an accurate result every time that you do this.
