Analogies: A is to B as C is to what

The answer is wrong whenever the description of the relationship is vague.

Part of the MatrixMind maths, science and reasoning guide · updated 13 October 2026

A visual analogy shows you a pair of figures with some relationship between them, then a third figure, and asks for the fourth. Written out it is the familiar form: A is to B as C is to what.

It is the purest test of one specific skill — describing a relationship precisely enough that it can be applied somewhere else. Everything that goes wrong with these puzzles goes wrong at the describing stage.

Precision is the whole of it

Suppose A is a small circle and B is a large circle. What is the relationship?

Each description sounds like the same observation. They are not. Given C as a small triangle, the first tells you almost nothing, the second gives you a size but leaves shading open, and only the third uniquely determines the answer.

This is why analogies reward writing things down. A relationship you have only felt is one you cannot check.

One relationship, described three ways
A B C ? ▲ -> ▲▲ ■ -> ? small two small small shaded shaded empty

Vague: 'there are more of them'. Better: 'the count doubled'. Precise: 'the count doubled, size unchanged, shading unchanged'. Only the last one tells you the answer is two small empty squares. Notice the shading in C differs from A — so a description that quietly assumed 'shaded' would produce the wrong answer with complete confidence.

Describe the change, not the figures

A common failure is describing what A and B are rather than what happened between them. 'A is a triangle and B is two triangles' is a description of the pair. 'The count doubled' is a description of the transformation, and only the transformation transfers to C.

The test: could you apply your description to a figure you have not seen yet? If not, it is a description of the figures rather than the relationship.

Relationship families

Most visual analogies use one of these, sometimes two together:

Run that list when you are stuck. It is short, and the answer is nearly always on it.

Check your rule backwards

Once you have a candidate answer D, test whether C-to-D describes the same relationship as A-to-B, stated the same way. If your description of A-to-B was 'rotated ninety degrees clockwise' then C-to-D must also be exactly that, not 'rotated somehow'.

This catches the most common analogy error, which is a relationship that holds loosely in both pairs but differs in a detail — rotated ninety in one pair and one-eighty in the other, both of which feel like 'it turned'.

When two answers both fit, your description is not precise enough yet. Go back and add a clause — usually about shading, size or handedness — rather than choosing between them. The extra clause will eliminate one.

The distractors here are unusually good

Analogy distractors are built from near-miss relationships: the right transformation applied to the wrong attribute, the right attribute transformed the wrong amount, or the transformation from A-to-B applied to A instead of C.

That last one catches people constantly. If the answer options include a figure that is obviously B modified, be suspicious — it is usually there to catch someone who lost track of which figure they were transforming.
