Figure Series & Analogy
A figure series changes by a consistent rule — rotation by a fixed angle, adding/removing an element, shading shifting one step, or a shape growing. Identify the single transformation from one figure to the next and continue it. Figure analogy (A:B :: C:?) applies the A→B change to C.
What changes between figures?
A figure series is built on one (sometimes two) consistent transformations. Check them in this order:
| Transformation | What to look for |
|---|---|
| Rotation | the whole figure turns a fixed angle each step (45°, 90°, 180°) |
| Reflection | the figure flips left-right or top-bottom |
| Addition / removal | an element (line, dot, side) is added or removed each step |
| Shading / movement | a shaded part moves one position (often clockwise) each step |
Rotation — the most common rule
Track one feature at a time. If a figure both rotates and changes shading, solve the rotation first, then the shading. A figure analogy (A:B :: C:?) is the same idea — find the change from A to B and apply the identical change to C.
✅ Solved examples
1. An arrow rotates 90° clockwise each step. After pointing up, then right, what is next?
Continue clockwise: down.
2. A figure adds one dot each step: 1, 2, 3 dots. Next?
4 dots.
3. A:B is "rotate 90° clockwise". If C points North, C:? is?
East (90° clockwise).
4. Shading moves one segment clockwise each step. After top, then right, next?
Bottom.
✏️ Practice — try these, take hints as needed
