From first figure to second figure all the arrows are reversed. Alternatively, the second figure is the mirror image of the first figure.
As we know that the mirror image always be opposite the original image across the given line. It will become opposite to the given line .As shown in given below .
Therefore , option C is required answer .
On the basis of above given question , we have
The mirror image always be opposite the original image across the given line. It will become opposite to the given line .As shown in given below .
Hence , option D is required answer .
2, 5, 8 are all three-dimensional figures.
3, 6, 9 are all (two-dimensional) triangles.
Consequently, when 4, 3, 1 and 5 are the numbers on the top faces, then 3, 4, 6 and 2 respectively are the numbers on the face touching the ground. The total of these numbers = 3 + 4 + 6 + 2 = 15.
The simplest rectangles are ABQP, PQNO, BCDN, NDEM, MEFL, LFJK, FGHR and RHIJ i.e. 8 in number.
The rectangles composed of two components each are ABNO, BCEM, NDFL, MEJK and FGIJ i.e. 5 in number.
The rectangles composed of three components each are ACDO, BCFL, NDJK and LGIK i.e. 4 in number.
There is only one rectangle i.e. BCJK composed of four components.
Total number of rectangles in the figure = 8 + 5 + 4 + 1 = 18.
