Question 42 of 45
42. Question
1 pointsWhat is the minimum number of straight lines that is needed to construct the figure?
Correct
The figure may be labelled 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.
