I think you have to draw a circle then draw a line that goes parralel to one tiny part of the circle. this ensures it only touches the circle at one place. make sure the line is straight too!
Think of 2 times 2 You would duplicate 2 two times 8 times 8 is 64 6 times 6 is 36 It’s kind of just adding an integer (any number) to the integer that is stated after it
