Muslim artists use math primarily to create designs with tessellations. Islamic art often features intricate geometric patterns that repeat and interlock, showcasing a deep understanding of symmetry, proportion, and mathematical principles. These designs can include complex shapes and patterns that exemplify the use of mathematics in creating aesthetically pleasing and harmonious artworks.
While some aspects like writing in a decorative way (calligraphy), making images the right size (proportions), and showing the time of the sunset (used in astronomy for prayer times) involve practical applications of math, the prominent use in art specifically focuses on geometric designs and tessellations.
