In this lesson, we not only carry out the construction but also explain the logic behind each move — why we choose certain points, how symmetry guides the process, and what geometric properties ensure accuracy. With simple reasoning and clear diagrams, you’ll understand both the “how” and the “why” of these constructions, making it easier to apply them in exams and classroom practice.
