On the basis of given figures in above question , we can see that
In each subsequent figure one square is added, the black dot moves along the side of square in clockwise direction and the arrow inside the circle rotates through 90° anti-clockwise.
Clearly , answer figure ( 3 ) will come on the place of ? in question figure .
3, 7, 9 are closed figures shaded by oblique line segments.
2, 4, 5 are figures composed of straight lines only.
Rule: Closed figures become more and more open and open figures become more and more closed.
According to given question figure ,
we can say that the mirror image always be opposite the original image across the given line. Given image will become opposite in mirror across the given line AB.
As we know that the mirror image always be opposite the original image across the given line. Given image will become opposite to the given line AB.As shown in given below .
From first figure to second figure the entire design rotates 90º anticlockwise.
All other designs have been made of three line segments whereas figure (4) has been made up of four line segments.
