What types of transformations does Escher use in his tessellations'?

M.C. Escher employs several types of transformations in his tessellations, including translation, rotation, reflection, and glide reflection. These transformations allow him to create intricate, interlocking patterns that often feature complex shapes and forms, such as animals and geometric figures. His work also explores the relationship between two-dimensional and three-dimensional spaces, often creating the illusion of depth and perspective. Through these techniques, Escher's tessellations achieve a harmonious balance between chaos and order.
