A rosette of circles
Draw 12 circles of radius 60, turning left 30 degrees after each, and change the pen colour to a different colour for each pair.
Learn
t.circle(60) draws a circle of radius 60. Turn a little and draw another circle, and another, and the circles overlap into a flower called a rosette. If you draw 12 circles you need to turn 360 / 12 = 30 degrees between them to come all the way round.
Your task
Draw 12 circles of radius 60, turning left 30 degrees after each, and change the pen colour to a different colour for each pair.
Stretch challenge
Draw 18 circles with a turn of 20 degrees. What is the rule linking the number of circles and the turn?
