![]() ![]() Use geometric tools to measure and draw angles.is the same as 30° in China.Īfter this lesson, students should be able to: These tools also help us communicate across different spoken languages and cultures since they are universal-that is, 30° in the U.S. Engineers rely on their tools to provide consistent ways of measuring, especially aspects such as length and angles, to enable modern feats of engineering from skyscrapers to satellites. Today, the same tools are used by engineers for creating precise design drawings for modern infrastructure, systems and products. Over time, these tools became more complex and enabled more accuracy and greater design precision. ![]() This lesson prepares students to conduct the associated activity in which they “solve the holes” for hole-in-one multiple-banked angle solutions, make their own one-hole mini-golf courses with their own geometry-based problems and solutions, and then compare their “on paper” solutions to real-world results.Īncient Egyptian and Roman engineers used geometry tools to create impressive structures and sites that still stand today. Through the lesson, students gain an awareness of the pervasive use of angles, and these tools, for design purposes related to engineering and everyday uses. After seeing some class practice problems and completing a set of worksheet-prompted problems, students share their methods and work. The lesson begins with a recap of the history and modern-day use of protractors, compasses and mirrors. Students learn about common geometry tools and then learn to use protractors (and Miras, if available) to create and measure angles and reflections.
