Make a list of figures you find interesting or special, and try to explain what is special about them.
Suggestion: you don\'t have to draw all the figures, just write down the minutes on the circle.
A five pointed star like this is called a \'pentagram\'.
How would you make such a pentagram?
A lot of figures have crossed lines. In a pentagram you can clearly see this, but there are also figures without these crossings. Here you can see some.
How can you make a figure without crossing lines?
You can also often see a hole forming in the center of the figure. Sometimes it\'s big and sometimes small.
When do you see a big hole and when is it small?
Try \'15 minutes\' and \'45 minutes\'. This will give you the same result. Try to make this work for other figures.
Please write down how you can always find two ways to make the same figure.
