Analogy— Concepts, Formulas & Shortcuts
- Name the transformation exactly: rotation (and by how much), reflection, addition or removal.
- Apply the SAME transformation, in the same direction, to the second pair.
- Rotation preserves handedness; reflection reverses it.
- A mirror image cannot be produced by any rotation in the plane.
- If the first pair changes element count, the second pair must change it by the same amount.
- Check the direction of rotation — clockwise and anticlockwise give different answers.

Q1.In a non-verbal analogy, the relationship in the first pair must be:
Easy- AReversed for the second pair
- BApplied identically to the second pair
- CIgnored
- DDoubled
Analogy question 1 of 8+Show Answer & Explanation
Answer: B. Applied identically to the second pair
Explanation: The second pair must undergo the very same transformation as the first.
Q2.If figure A becomes B by rotating 90° clockwise, then C becomes D by:
Easy- ARotating 90° anticlockwise
- BRotating 90° clockwise
- CReflecting vertically
- DRotating 180°
Analogy question 2 of 8+Show Answer & Explanation
Answer: B. Rotating 90° clockwise
Explanation: The identical transformation must be applied, including its direction.
Q3.If A is the mirror image of B, the transformation involved is:
Moderate- ARotation
- BLateral inversion
- CTranslation
- DEnlargement
Analogy question 3 of 8+Show Answer & Explanation
Answer: B. Lateral inversion
Explanation: A mirror image reverses left and right, which is lateral inversion.
Q4.A figure and its water image differ by:
Moderate- AA left-right flip
- BA top-to-bottom flip
- CA 90° rotation
- DNo change
Analogy question 4 of 8+Show Answer & Explanation
Answer: B. A top-to-bottom flip
Explanation: A water image reflects the figure in a horizontal surface, flipping top and bottom.
Q5.If the first pair doubles the number of sides of a polygon, the second pair must:
Easy- AHalve the sides
- BDouble the sides
- CKeep them equal
- DAdd one side
Analogy question 5 of 8+Show Answer & Explanation
Answer: B. Double the sides
Explanation: The transformation is doubling, so it applies unchanged to the second pair.
Q6.Which transformation can NEVER be achieved by rotating a figure within the plane?
Difficult- A90° turn
- B180° turn
- CMirror reflection
- D270° turn
Analogy question 6 of 8+Show Answer & Explanation
Answer: C. Mirror reflection
Explanation: Reflection reverses handedness, which no in-plane rotation can do.
Q7.If the first pair removes one element from the figure, the second pair should:
Easy- AAdd one element
- BRemove one element
- CRemove two elements
- DLeave it unchanged
Analogy question 7 of 8+Show Answer & Explanation
Answer: B. Remove one element
Explanation: The analogy requires the same operation, so one element is removed again.
Q8.Rotating a figure by 180° clockwise is equivalent to rotating it:
Moderate- A90° anticlockwise
- B180° anticlockwise
- C270° clockwise
- D360° clockwise
Analogy question 8 of 8+Show Answer & Explanation
Answer: B. 180° anticlockwise
Explanation: A half turn reaches the same orientation whichever way you go round.
Analogy — Frequently Asked Questions
How do I tell a rotation from a reflection?+
Rotation preserves the arrangement's handedness; reflection reverses it. If the transformed figure looks like the original viewed in a mirror, it cannot be a rotation.
Why does direction of rotation matter?+
Because 90° clockwise and 90° anticlockwise produce different orientations. Only a 180° turn gives the same result in either direction.
