Question

Draw a line segment of length 7.3 cm using a ruler.

Answer 1

Hint: First, before proceeding for this, we must know that it can be done by using the steps used for construction in geometry. Then, firstly we start with considering a ray l which is approaching infinity at one side and then we will mark a point A on the starting of the line so as to get a fixed starting point. Then, from point A, we use a compass and a scale and open the compass from 0cm on the scale to 7.3 cm on the scale and draw an arc on the line l to get the length on the line.

Complete step by step answer:
In this question, we are supposed to draw a line segment of length 7.3 cm using a ruler.
So, before proceeding for this, we must know that it can be done by using the steps used for construction in geometry.
Now, firstly we start with considering a ray l which is approaching infinity at one side as shown in the figure.

Then, we will mark a point A on the starting of the line so as to get a fixed starting point as shown in the figure.

Then, from point A, we use a compass and a scale and open the compass from 0cm on the scale to 7.3 cm on the scale.
Then, using the opened compass of length 7.3 cm, draw an arc of length 7.3 cm on the ray l from point A as starting point as shown in the figure.

Now, we will mark the point where the arc cuts the line l as B as shown in the figure.

Hence, we get the line of length 7.3 cm as AB by using the ruler.
Note:
Now, to solve these types of the questions we need to know some of the basic things about the construction of figures. So, the most important thing is explained above in the question which is how to make the length using the compass and scale so that we can get any length bisected at any angle.
