Geometric Descriptive: Exercises Discussion and Perpendicularity

This lecture covers the discussion of exercises related to geometric descriptive concepts, including the intersection of a line with an opaque plate, perpendicular lines to a plane, and the use of GeoGebra software. The course aims to enhance students' ability to visualize geometric situations through sketches, understand points, lines, and planes, solve spatial geometry problems using Monge's representation techniques, and work with spheres, cones, and cylinders. The instructor emphasizes the importance of attending in-person classes and provides examples and exercises to reinforce the learning process.
