Question

Which figure is the odd one out? 

• A. A
• B. B
• C. C
• D. D
• E. E

Hint:

To quickly solve "rotation vs. reflection" problems, trace the elements in a clockwise direction. For example, in A, B, D, and E, the sequence of shapes follows the same clockwise order. In Figure C, that order will be reversed (counter-clockwise), which immediately identifies it as a reflection/odd one.

Answer 1

The Correct Option is C

Concept: "Odd One Out" problems in non-verbal reasoning usually involve finding a figure that cannot be created by simply rotating the others. If a figure is a mirror image (reflection) rather than a rotation, it is considered the odd one.

Step 1: Identifying the common pattern.
Each square contains a specific geometric arrangement of lines forming triangles and a quadrilateral. Let's pick a reference point, such as the quadrant containing the "blank" triangle or the specific orientation of the internal diagonal lines.


Step 2: Testing for Rotations.
If you rotate Figure A 90° clockwise, you get Figure B. If you rotate Figure B 90° clockwise, you get Figure D. If you rotate Figure D 90° clockwise, you get Figure E. Figures A, B, D, and E are all the same pattern, just viewed from different angles (rotations of each other).


Step 3: Analyzing Figure C.
Figure C cannot be obtained by rotating any of the other figures. If you try to rotate Figure A to match the "blank" area of Figure C, you will notice that the internal lines (the diagonal and the bisectors) are reflected. Figure C is a mirror image of the others, making it the odd one out.
