This lecture provides an overview of the Descriptive Geometry course, focusing on its objectives and applications. The instructor discusses the importance of visualizing geometric situations in two dimensions to solve spatial problems in three dimensions. Key topics include the representation of geometric objects, the use of drawing techniques, and the application of software tools like GeoGebra for defining and manipulating geometric figures. The course aims to develop students' abilities to illustrate geometric situations through sketches and to apply techniques such as Monge's representation, axonometry, and perspective. The lecture emphasizes the relevance of these skills in various fields, including architecture, mathematics, and physics. The instructor also outlines the course structure, including the schedule for lectures and exercises, and encourages students to engage actively with the material. Overall, the lecture sets the stage for a comprehensive exploration of Descriptive Geometry, highlighting its practical applications and the skills students will acquire throughout the course.
