Analogy
What you will learn
- How to read an analogy in the form A is to B as C is to ?.
- How to name the relationship between the first pair before applying it to the second pair.
- How analogies can be based on words (function, opposites, part-whole) or numbers (square, double, add a fixed amount).
Key concepts
Level 1 — Simple word relationships
Verbal: Find how the first two words are connected, then find the matching word for the third.
Example: Bird is to Nest as Bee is to ? -> Hive (each animal's home).
| Analogy | Relationship |
|---|---|
| Foot : Shoe :: Hand : Glove | covering worn on the body part |
| Cow : Calf :: Dog : Puppy | baby of the animal |
Level 2 — Number relationships
Verbal: The rule connecting the numbers could be squaring, doubling, or adding a fixed number.
Example: 3 is to 9 as 4 is to ? -> 16 (squaring rule: 3x3=9, 4x4=16).
Level 3 — Deeper relationships
Verbal: Relationships can be opposites, part-to-whole, or worker-to-material.
Worked example
Wheel is to Car as Page is to ?
Step 1 - Wheel is a part of a Car (part-to-whole)
Step 2 - Apply same relation: a Page is a part of a Book
Answer: Book
5 is to 25 as 6 is to ?
Step 1 - 5 squared = 25, so the rule is 'square the number'
Step 2 - 6 squared = 36
Answer: 36
Common mistakes
| Mistake | Why it happens | Fix |
|---|---|---|
| Guessing the answer without naming the rule | Rushing | Say the relationship in words first |
| Mixing up part-to-whole direction | Confusing which is the part | Check: is the smaller thing part of the bigger one? |
| Using the wrong number operation | Trying addition when it is really squaring | Test the rule on the first pair before applying it |
| Picking an opposite when the relation is 'function' | Not checking category of relationship | Reread both pairs carefully |
Quick check
- Petal is to Flower as Leaf is to ?
- 4 is to 8 as 5 is to ? (doubling rule)
- Thief is to Steal as Liar is to ?
- Stretch: Ounce is to Weight as Metre is to ? (unit and what it measures)
Revision tip: Turn the analogy into a sentence: 'A goes with B in the same way that C goes with ___.'
