Final answer:
M.C. Escher used tessellation with geometric shapes like triangles, squares, and hexagons in his designs.
Step-by-step explanation:
M.C. Escher used the tessellation technique in his designs. A tessellation is a pattern made by repeating a shape over and over without any gaps or overlaps. Escher often used the regular division of the plane with geometric shapes like triangles, squares, and hexagons to create his intricate designs.
