A circle has a total angle of 360 degrees, therefore you would divide this by 20 and get 18. So if you divide the circle like a pizza each slice has a centre angle of 18 degrees. Use a protractor to make your angles from the centre of the circle.
Very engaging. My son is 12 and we are home educating - extremely helpful for me as my waldorf geometry is a little rusty.

Sir how to do 20 equal divisions on circle ? To start this exercise .
