Origametry? Yes, the art of origami involves several geometric components! In this lesson, students will create a decahedron through a paper folding activity and determine how geometric concepts, such as parallel lines, perpendicular lines, and bisecting lines, connect to the ancient art form.
- Make formal geometric constructions with a variety of tools and methods (compass and straightedge, string, reflective devices, paper folding, dynamic geometric software, etc.).
- Copying a segment; copying an angle; bisecting a segment; bisecting an angle; constructing perpendicular lines, including the perpendicular bisector of a line segment; and constructing a line parallel to a given line through a point not on the line.
