Teorema de Pitágoras: Fórmula, Nomenclatura e Demonstração

Section role: supports the 'Formalização: A Matemática de Pitágoras' section while the teacher systematizes the discoveries made in the previous groups and presents the mathematical formalization. Slides: (1) Title — 'A Matemática de Pitágoras'; (2) A Equação Fundamental — bullets: presentation of the formula a² = b² + c², meaning of each variable; (3) Nomenclatura dos Lados — bullets: definition of Hipotenusa as the side opposite the right angle and the longest side, definition of Catetos; (4) Demonstração por Semelhança — bullets: visual breakdown of how splitting the right triangle by the altitude relative to the hypotenusa creates similar triangles; (5) Exemplo Prático Resolvido — bullets: application of the formula with an escalator of 5m leaning against a wall 3m away from the base, finding the height; (6) Vídeo Explicativo — bullets: introduction to Professora Gis video for visual reinforcement; (7) Conexão com o Cotidiano — bullets: tying back to the initial ramp challenge from Section 1 and setting up the individual practice in Section 4. Closing slide: 'Qual dos lados é sempre o maior e por quê?' — hands control back to the teacher for immediate Q&A.
