Find the minimum number of straight lines required to make the given figure.

[A]. 16
[B]. 17
[C]. 18
[D]. 19

Answer: Option B


The figure may be labelled as shown.

The horizontal lines are IK, AB, HG and DC i.e. 4 in number.

The vertical lines are AD, EH, JM, FG and BC i.e. 5 in number.

The slanting lines are IE, JE, JF, KF, DE, DH, FC and GC i.e. 8 is number.

Thus, there are 4 + 5 + 8 = 17 straight lines in the figure.

Why did not you consider as the EL and LF are consider as lines?

Why did not you take the EF as straight lines?

Sharmie said: (Oct 3, 2011)  
How can you consider IE and KF as straight lines?

Rakesh said: (Oct 14, 2011)  
@Suresh EL and LF are on AB so AB alone is sufficient to draw the givendiagram

@Sharmie any line joining two point is a straight line.

Rohit said: (Jul 31, 2012)  

We are asked to count minimum so we can just take it on AB.

Tushar said: (May 5, 2013)  
Why did we not consider EF as horizontal?

Azhar said: (Jun 14, 2013)  

Stated as rohit and Rakesh, We can take minimum Qty of line. Since Ef on AB, AB is sufficient.

Shivani Agrawal said: (Sep 23, 2013)  
If we are taking minimum lines. Then why we consider DE as slanting line. DH was enough.

Nikhil said: (Sep 24, 2014)  
Why did not you take HM and MG?

M.PRADEEP said: (Oct 24, 2014)  
Why did not you take ML, HM, MG?

Akhil Agrawal said: (Oct 27, 2014)  
Because here we are asking min. Number of straight lines so it will be HG simply.

Amar said: (Mar 20, 2015)  
Why not take EF as straight line?

Nivetha said: (May 6, 2015)  
@Amar EF are already on AB. So we can't consider that as line.

Sunny said: (May 24, 2015)  
Best way is to draw the figure then itself, it will be easy to find rather than numbering.

I have doubt that your method is right or wrong.

Gokul said: (Sep 13, 2015)  
Any short cut to find answer.

Any short cut method to find answer.

CHANU said: (Sep 23, 2015)  
Hello by counting I have got 25 lines. I think your's assumption is false.

Anil Reddy said: (Dec 23, 2015)  
Why are counting slanting lines? They are not straight lines.

Vivek said: (Feb 20, 2016)  
It's ask about straight line not horizontal, vertical, slanting.

Manaswi said: (Aug 17, 2016)  
Why isn't JM considered as one of the lines?

Sofia said: (Oct 1, 2016)  
Is there any formula to find the number of lines?

Soham Seth said: (Oct 25, 2017)  
Why didn't you consider IJ and JK?

Sudharshan said: (Jun 23, 2018)  
No.of nodes-9+2(no.of inner nodes)4.

Rebel said: (Oct 25, 2018)  
why you did not take EF? Please explain me.

Lavanya said: (Jan 23, 2019)  
Why you didn't take EF as a straight line?

Samiksha said: (Feb 5, 2019)  
Jm can also be one line. Right?

Anirudh said: (Oct 31, 2019)  
Tell me the proper method to solve it.

Safari said: (Nov 17, 2019)  
EF is a horizontal line so why it does not count? If it includes the answer is 5+5+8=18.

Ritu said: (Nov 19, 2019)  
I didn't understand this question. Can someone please explain to me?

Steve Rajesh said: (Dec 7, 2019)  
@Ritu its simple you just add vertical line+horizontal line+slant or inclined line.

Krishna Neupane said: (Apr 22, 2021)  
17 is the correct answer.

PALLAVI R C said: (May 3, 2021)  
I think 18 is the correct answer.

Pari Khan said: (Jul 25, 2021)  
18 is the correct answer.

Anju said: (Aug 27, 2021)  
Yes, I got 18 lines. So I think option C is the right answer.

John Mathew said: (Dec 3, 2021)  
They have not asked us to count line segments. They have asked us to find out minimum number of straight lines required to make figure.

Shreya said: (Feb 21, 2022)  
I am not understanding this. Anyone, kindly explain this.

Saranya said: (Jul 4, 2022)  
Horizontal lines+ vertical lines+ inclined lines = total no of lines .
H -> 4
V -> 5
I -> 8

So, 17 is the answer.

Astro said: (Sep 21, 2022)  

First find out simple horizontal lines which can be IK, HG, AB & DC.
Now cross those out if your doing this on a paper.
Now keep finding vertical and slanting.
Then simply add all the lines you got together.
