This is an improvement on previous Sierpinski Triangle project https://pythonturtle.academy/sierpinski-triangle/ by adding Red, Green, and Blue colors to the triangles.
In other related projects, we draw a pentagon spiral and a square spiral. Now draw a dodecagon spiral with 12 sides. Also make the grayscale of dodecagons gradually grow lighter
In a previous project, you drew Archimedean Spiral, in which radius increase linearly with the angle. In Fermat’s spiral, radius increases in proportion to the square root of the angle.
