Question

Face $ABCD$ of a cubical block is transformed to $A^{\prime }{B}^{\prime }{C}^{\prime }{D}^{\prime }$. What type of transformation has taken place?

• A. Rotation of 180° clockwise about the origin
• B. Rotation of 180° counterclockwise about the origin
• C. Either A or B
• D. Neither A nor B

Answer 1

The correct option is C Either A or B

As coordinate A lies on the origin, when rotated ${180}^o$ clockwise or counterclockwise, the resultant image in both rotations will lie in the third quadrant with the same shape and size.
