Symmetry in Geometry

This lecture introduces a new course organization, emphasizing the importance of maintaining a dedicated time for geometry in the weekly schedule. The instructor encourages students to take advantage of the resources offered by EPFL, including additional tutoring sessions. The lecture delves into the concept of modern symmetry, contrasting it with ancient geometry and highlighting its cultural significance. Through a series of videos, students will explore various isometries, focusing on axial reflection as the foundational element. By the end of the semester, students will apply their knowledge of modern symmetry to analyze regular polyhedra in space, preparing them for future topics on symmetries in regular polygons and decorative architectural friezes.
