Ejercicio 2 - Corte y sección de un tetraedro en diédrico 🤔 PAU Comunidad Valenciana Junio 2026

Do you know how to obtain the cut and section of a tetrahedron in the dihedral system? 📐 In this video, we solve Exercise 2 from the PAU (University Access Exam) for the Valencian Community in June 2026, focusing on the cut and section of a tetrahedron in the dihedral system. Step by step, we'll see how to determine the points of intersection between the plane and the edges of the tetrahedron, correctly obtaining the section produced by the cutting plane and representing it in plan and elevation views. 📘 This type of exercise is very common in the PAU/EBAU exams, within the descriptive geometry, polyhedra, and sections section. 📌 In the video, you will learn: How to work with a tetrahedron in the dihedral system. How to locate the points of intersection of the plane. How to obtain the resulting section. Correct representation in plan and elevation views. Tips to avoid mistakes on the exam. A fundamental exercise for mastering polyhedral sections in technical drawing. Become a member of this channel to enjoy exclusive benefits:    / @dibujotécnicopasoapaso
