ConstruÃÃes com rÃgua e compasso e algumas aplicaÃÃes / Constructions with ruler and compass and some applications

Emanuel Oliveira de AraÃjo 29 September 2015 (has links)
coordenadoria de aperfeiÃoamento de pessoal de ensino superior / Este trabalho apresenta construÃÃes bÃsicas realizadas com rÃgua e compasso que foram desenvolvidas por civilizaÃÃes antigas com o intuito de realizar tarefas do cotidiano e construir monumentos. Para isso, os procedimentos utilizados eram baseados em retas e circunferÃncias com a intenÃÃo de encontrar a medida adequada para estas realizaÃÃes. Mostraremos neste trabalho as principais construÃÃes realizadas com esses instrumentos, como alguns polÃgonos e algumas medidas algÃbricas. Analisaremos essas construÃÃes de forma simples e algÃbrica para justificar a veracidade de suas conclusÃes. Entenderemos tambÃm o conceito de nÃmeros construtÃveis e suas caracterÃsticas. Aprenderemos a identificar se um nÃmero pode ou nÃo ser construÃdo com a rÃgua e o compasso. Com isso, poderemos verificar com melhor clareza os problemas clÃssicos da geometria e o real motivo de nÃo haver soluÃÃes de construÃÃo para estes problemas. A finalidade deste trabalho à recordar um pouco do desenvolvimento da Geometria e mostrar ao aluno que algumas fÃrmulas e equaÃÃes podem ser desenhadas para que sua soluÃÃo seja revelada. / This paper presents basic constructions made with ruler and compass were developed by ancient civilizations in order to perform daily tasks and build monuments. For this,the procedures used were based on lines and circles with the intention of finding the appropriate measure for these achievements. We show in this paper the main buildings made with these instruments, such as polygons and some algebraic measures. We analyze these buildings simply and algebraic way to justify the veracity of its findings. Also we will understand the concept of constructible numbers and characteristics. We learn to identify a number may or may not be constructed with ruler and compass. With this, we can see with clarity the classic problems of geometry and the real reason there is no building solutions to these problems. The purpose of this work is to recall some of the development of geometry and show the student that some formulas and equations can be designed so that your solution is revealed.
