AI Drawing Prompt Reference

Draw a tessellation pattern made of congruent triangles. Start with one triangle and connect the midpoints of its three sides to divide it into four smaller congruent triangles. Then reflect the original triangle and its subdivisions across each side midpoint to generate adjacent triangles, creating a symmetric arrangement around the original vertices and edges. The final image shows a seamless tiling of the plane by identical triangles, demonstrating periodic geometric transformations.
