AI Drawing Prompt Reference

Draw a pizza with center point A and edges points C and B, connecting A to C and A to B with line segments. Create a sector by rotating points C and B around point A. Use vectors and rotations to create pizza slices, ensuring they intersect the sector edges. Finally, rotate and move the slices to create multiple slices, forming a complete pizza appearance.
