Methods To Draw A Line Segment

We see a number of objects of different shapes and sizes in our day to day life. They help us shape and understand the basic geometrical ideas in our mind. In fact, basic geometry is nothing but the study of points, lines, line segments, angles, surfaces, and solids. Here we will focus the discussion on line segments. A line segment is a part of a line with two endpoints. It is one of the essential elements of practical geometry as it facilitates the construction of geometric shapes and figures. This segment will enable you to learn how to draw a line segment of a given length.

The Line Segment

Before we move over to the procedure to learn how to draw a line segment, it is required for you to keep some of its characteristics in mind.

  • A line segment has a distinct beginning and end.
  • It is the shortest distance between two points.
  • It has a fixed length.
  • It is possible to measure the length of a line segment using a ruler and represent it by a diagram.

How to Draw a Line Segment of a Given Length?

To draw a line segment of a given length, we can employ either of the given methods:

  • Using a ruler
  • Using ruler and compasses

Using a Ruler

You are required to draw a line segment of length 5 cm. The simplest method is by using a ruler. You mark two points using a ruler which are at a distance of 5 cm from each other. You mark the points as A and B and join them. You get a line segment AB of length 5 cm

However, it is to be noted that if you do not look straight down at the ruler, you might end up capturing an incorrect distance. A more accurate method for the same is described below.

Using Ruler and Compasses

The steps to draw a line segment of length 5 cm using ruler and compasses are:

  • Step 1: Draw a line of any length. Mark a point A on the line, which is the starting point of the line segment.
  • Step 2: Using a ruler, place the pointer of the compass 5 cm apart from the pencil’s lead.

  • Step 3: Place the pointer of the compass at A and mark an arc on the line with the pencil point.

  • Step 4: Mark the point where the arc and the line intersect as B.
  • Step 5: AB is the required line segment of length 5 cm.
