Question

Draw a line segment of length $7.3cm$ using a ruler and a compass.

Answer 1

Hint: To draw a line segment we have to use the fact that a line segment is a straight line bounded between two endpoints. We need to follow a few steps such as drawing a line with any measurement then marking a starting point as A and measure the line with the help of ruler and compass of $7.3cm$ and mark an endpoint.

Complete step by step solution:
Here, we are asked to draw a line segment of length $7.3cm$ using a ruler and pencil.
A line has no endpoints and extends endlessly in both directions. If we mark two points A and B on it and pick this segment separately, it becomes a line segment. A line segment is a straight line bounded between two fixed points. It is of finite length. A line segment is characterized by the label of its endpoints and its length.
Now we will draw a line segment with the given measurement. To do so, we need a pencil, sheet, ruler, compass and a few steps to follow.
Step: 1
We will draw a line of any length with a pencil and scale on a sheet. Then will mark a point A on the line, which is the starting point of the line segment.

Step: 2
By using a ruler, we will place the pointer of the compass at $7.3cm$ part from the pencil’s lead.
Step: 3
By placing the pointer of the compass at A we will mark an arc on the line with the pencil point.

Step: 4
Now, we will mark the arc and the line intersects as B.

Step: 5
AB is the required line segment of length $7.3cm$

Hence, we have drawn a line segment AB of length $7.3cm$ .

Note: Students must keep in mind that the line segment should be straight and must be drawn with a pencil and ruler. It’s necessary to label both the end points and measurement of line segments. All the constructions must be clear and non-messy and should be drawn using a pencil only.
