Question

The steps of construction of an $\angle AOB={45}^o$ is given in jumbled order below:
1. Place compass on intersection point.
2. Place ruler on start point and where arc intersects perpendicular line.
3. Adjust compass width to reach start point.
4. Construct a perpendicular line.
5. Draw $45$ degree line.
6. Draw an arc that intersects perpendicular line.
Which step comes first?

• A. $1$
• B. $3$
• C. $4$
• D. $5$

Answer 1

The correct option is C $4$

Correct sequence is :

1. Construct a perpendicular line .

2. Draw an arc that intersect the perpendicular line.

3. Adjust the compass width to reach the start point .

4.Place compass on intersection point.

5. Place ruler on start point and where the arc intersects the perpendicular line.

6. Draw $45$ degree line.

So the first step is $4$

Option $C$ is correct.
