A straight edge or a ruler are used to construct straight lines. In math a compass is an object used to draw accurate circles and arcs parts of circles, or curves. In math, a compass is something that makes a circle and it also measures circumference. How to make a circle: A compass either has led in it or you stick a pencil in it, but it depends on what kind of compass it is. If you want to make a big circle, you expand the 2…. Circle is a shape. We have gotten to know a lot from circles.

Year 8 Interactive Maths - Second Edition. A circle is a set of points in a plane that are the same distance from a fixed point called the centre. These set of points form the perimeter of the circle. The radius is the distance from the centre of the circle to any point on its perimeter. A secant is a line that passes through any two points on a circle. A chord is a line that joins two points on the circumference of a circle. The diameter is a chord that passes through the centre of a circle.

The instrument used to construct or draw circles is called a pair of compasses, although it is often known either as compasses or simply as a compass. A pair of compasses usually consists of a joined pair of "legs", one of which has a sharp point, and the other of which holds a pencil. The sharp point is pushed lightly into the paper and acts as a pivot, while the other leg can be swung around it to draw an arc, or a complete circle. A pair of compasses are use to construct circles and arcs of circles. It is "a pair of compasses" - usually called a compass.

A pair of compasses , also known as a compass , is a technical drawing instrument that can be used for inscribing circles or arcs. As dividers , they can also be used as tools to measure distances, in particular on maps. Compasses can be used for mathematics , drafting , navigation and other purposes. Compasses are usually made of metal or plastic, and consist of two parts connected by a hinge which can be adjusted to allow the changing of the radius of the circle drawn. Typically one part has a spike at its end, and the other part a pencil, or sometimes a pen. Prior to computerization, compasses and other tools for manual drafting were often packaged as a "bow set" [1] with interchangeable parts.

Plane or Euclidean geometry is the branch of mathematics that studies figures such as points, lines, and angles constructed only with the use of the straightedge and the compass. It is primarily concerned with such problems as determining the areas and diameters of two-dimensional figures. To determine geometric designs four important tools of geometry — compass, straightedge, protractor, and ruler — are used. Technically a true geometric construction with Euclidian tools, originally used by the ancient Greeks, uses only a compass or a straightedge. The ruler and protractor were later inventions. Today, the study of geometry is an essential part of the training of such professionals as mathematicians, engineers, physicists, architects, and draftspersons.
