A compass, also commonly known as a pair of compasses, is a technical drawing instrument that can be used for inscribing circles or arcs. As dividers, it can also be used as a tool to mark out …

These constructions use only compass, straightedge (a ruler, but not using the numbers) and a pencil. This is the "pure" form of geometric construction: no numbers involved! Learn these …

It is possible to construct circles, arcs and bisect lines or angles using compass. Find more about parts of a compass, steps to draw with compass and examples.

In geometry, a compass is a tool that can be used to draw circles and arcs, as well as to copy line segments. Many plane figures can be constructed with only a compass and a straightedge.

We can use the following applet to simulate geometric constructions using straightedge and compass.

The word construction in geometry has a very specific meaning: the drawing of geometric items such as lines and circles using only compasses and straightedge or ruler.

The geometry of compasses was developed independently by G. Mohr in Denmark in 1672, and by L. Mascheroni in Italy in 1797. The easiest way, however, to show that compasses are …

This became almost like a puzzle game for mathematicians: trying to find ways to “construct” different geometric shapes using just a straight-edge and compass.

Compass drawing means using a mathematical compass to construct circles, arcs, and precise geometric figures. This technique is vital in geometry for drawing accurately measured shapes, …

In this video we discuss some common must-know geometry constructions with a compass and straightedge.
