Trefoil, comes from Lantin, means three-leaved plant. It is a shape used in architecture and Christian symbolism. For more details about this shape checkout this Wikipedia article. Hint: This shape
In level 1 project: three tilted squares (https://pythonturtle.academy/three-tilted-squares/), you drew only three tilted squares. Now use a loop to draw 60 evenly spaced out squares.
