1:

दिइएको चित्र बनाउन आवश्यक सीधा रेखाहरूको न्यूनतम संख्या पत्ता लगाउनुहोस्।

Correct Answer : 17

Explanation:

The figure may be labeled 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.

दिइएको चित्र बनाउन आवश्यक सीधा रेखाहरूको न्यूनतम संख्या पत्ता लगाउनुहोस्।

Correct Answer : 13

Explanation:

The figure may be labeled as shown.

The horizontal lines are IJ, AB, EF, MN, HG, DC and LK i.e. 7 in number.

The vertical lines are AD, EH, IL, FG, BC and JK i.e. 6 in number.

Thus, there are 7 + 6 = 13 straight lines in the figure.


3:

दिइएको चित्र बनाउन आवश्यक सीधा रेखाहरूको न्यूनतम संख्या पत्ता लगाउनुहोस्।

Correct Answer : 11

Explanation:

The figure may be labeled as shown.

The horizontal lines are DE, FH, IL and BC i.e. 4 in number.

The slanting lines are AC, DO, FN, IM, AB, EM and HN i.e. 7 in number.

Thus, there are 4 + 7 = 11 straight lines in the figure.


4:

दिइएको चित्र बनाउन आवश्यक सीधा रेखाहरूको न्यूनतम संख्या पत्ता लगाउनुहोस्।

Correct Answer : 14

Explanation:

The figure may be labeled as shown.

The horizontal lines are AK, BJ, CI, DH and EG i.e. 5 in number.

The vertical lines are AE, LF and KG i.e. 3 in number.

The slanting lines are LC, CF, FI, LI, EK and AG i.e. 6 in number.

Thus, there are 5 + 3 + 6 = 14 straight lines in the figure.a


5:

दिइएको चित्र बनाउन आवश्यक सीधा रेखाहरूको न्यूनतम संख्या पत्ता लगाउनुहोस्।

Correct Answer : 13

Explanation:

The figure may be labeled as shown.

The horizontal lines are AE and JF i.e. 2 in number. The vertical lines are AJ, CH and EF i.e. 3 in number.

The slanting lines are AG, BF, JD, IE, AB, DE, JI and FG i.e. 8 in number.

Total number of straight lines needed to construct the figure = 2 + 3 + 8 = 13.
