AI Drawing Prompt Reference

Draw a geometric construction of a regular triangle and a pyramid, showcasing regular polygons, midpoints, and vector operations. Start by constructing a regular triangle, then build a pyramid on its base, marking the midpoints of each side and using vectors to represent relationships between key points. Begin with the base triangle and progressively add the sides to complete the pyramid, highlighting the application of spatial geometry and vectors.
