Question

To construct a perpendicular to a line ($L$) from a point ($P$) outside the line, steps are given in jumbled form.Identify the second step from the following.
1)Draw line $PQ$.
2)Draw a line $L$ and consider point $P$ outside the line.
3)Take $P$ as a center, draw $2$ arcs on line $L$ and name it as points $A$ and $B$ respectively.
4)Taking $A$ and $B$ as a center one by one and keeping the same distance in compass, draw the arcs on other side of the plane.The point where these arcs intersect name that point as $Q$.

• A. $4$
• B. $3$
• C. $2$
• D. $1$

Answer 1

The correct option is B $3$

The correct sequence is:

Step 1. Draw a line $L$ and consider a point $P$ outside the line.

Step 2. Take $P$ as center and draw two arcs on line $L$ ans name the points $A$ and $B$ respectively.

Step 3.Taking $A$ and $B$ as centres one by one and keeping the same distance in compass , draw the arcs on other side of the plane .The point where these arcs intersect name that as $Q$

Step 4. Draw line $PQ$

So the second step is $3$

Option $B$ is correct.
