Right here we’ll speak about making a line phase. We all know how to attract a line phase of a sure size. To illustrate we wish to draw a line phase 4.5 cm lengthy.

We observe the steps given under:

**Step I:** We place a scale on a sheet of paper as proven under.

**Step II:** We place the sharp finish of the pencil on the level that coincides with 0 on the size and name it A.

**Step III:** We mark one other level B, which corresponds to the fifth millimeter part after the 4th centimeter. (1 small division = 1 mm.)

**Step IV:** We join factors A and B by drawing a line phase with a fine-tipped pencil. The size of the road phase AB is 4.5 cm.

Drawing a Line Section:

Now let’s discover ways to draw a line phase of a sure size.

**Step I:** Place the ruler on the paper. Then mark the 2 P and Q factors towards the 0 and 9 marks of the size.

**Step II:** Maintaining the size even, transfer the pen alongside the sting of the size from P to Q. The size of the road phase PQ is 9 cm.

Suppose you should draw a line phase AB with a size of seven.7 cm.

Place the ruler on the paper.

Mark one level towards the ‘0’ mark and one other level towards the 7.7 cm mark.

Join the dots by urgent the size evenly and shifting the tip of the sharp pencil alongside the sting of the size.

Take away the size and title the factors A and B.

The drawn line phase is 7.7 cm.
