Geometry without compass, using R300Mv2 Flexible Mathematics Ruler. Including 2D and 3D shapes used in geometry and key information for arithmetic, trigonometry and algebra.
Geometry has long been a study of shapes, space, and the relationships between them. For centuries, the compass and straightedge have been iconic tools of this ancient discipline. But what if we asked a radical question: Can you do geometry without circles? Meet the parallel-straightedge, also known as a parallel ruler. Unlike the traditional single straightedge, this tool allows us to draw precise parallel lines with ease. It opens up a fascinating world of geometric exploration—without the need for a compass. https://mathomat.com.au/collections/a... So next time you pick up a ruler, remember—there’s a whole world of geometry waiting to be explored, no compass required.
Can you do geometry without circles? Meet the parallel-straightedge, also known as a parallel ruler. Unlike the traditional single straightedge.
Meet the double-straightedge, also known as a parallel ruler. This tool allows us to draw precise parallel lines with ease.
Can you do geometry without circles? Here I show how to bisect a line segment without circles using the double-straightedge.
Meet the double-straightedge, also known as a parallel ruler. Here I show how to construct a perpendicular to a given line segment.
Here I show how to construct a perpendicular to a given line through a given point using the double-straightedge, also known as a parallel ruler.
Here in the video, I show how to bisect a given angle using the double-straightedge, also known as a parallel ruler.
Here I show how to cut of a given length from another line segment, using the double-straightedge. All without the use of circles!
Here I show how to use the tool to double a given line segment using the double-straightedge—without the need for a compass.
All of classic geometry can be done with just ONE tool - the parallel straightedge. See how to construct a parallel line in this video!
Here's a better way to do geometry, creatively simplify much of geometry by using an everyday tool: a regular ruler—the double straightedge.
Here I show how to construct parallel line through a given point WITHOUT a compass and WITHOUT circles! The ideas are credited to Desargues.
