Embedded and hidden figure questions test visual discrimination. A simple target shape is concealed inside a larger drawing, often with extra lines, a changed size, or a rotation. Your task is to find the complete target without adding or removing any of its essential lines.

1. What to compare

• Line count: the target must contain the same required sides, curves, and intersections.
• Relative position: note which line joins which corner and whether a segment lies inside or outside a shape.
• Orientation: the target may be rotated, but it is usually not reflected unless the question permits it.
• Proportion: a target may be larger or smaller while preserving its structure.

2. A reliable search method

1. Study the target first. Identify its most distinctive feature, such as a unique angle, curve, or crossing.
2. Ignore the target's overall size and scan each option for that distinctive feature.
3. Trace the target line by line within a candidate figure.
4. Allow extra lines in the larger figure, but do not allow a missing target line or a changed connection.
5. Check rotation before rejecting a candidate; then check whether the figure has been mirror-reversed.

3. Rotation and reflection

Rotation changes the direction in which a figure faces but keeps the order of its connections intact. Reflection reverses the figure's handedness. For example, a shape with a short branch on the right remains right-handed after rotation, but the branch moves to the opposite side in a mirror image.

4. Handling distracting lines

• Extra lines may cross the target or extend beyond its corners; they do not invalidate a match.
• Use only the segments needed to reconstruct the target.
• Do not join two separate segments across a gap.
• Do not treat a curved line as a straight line, or vice versa.
• Start from a rare feature instead of trying to recognize the whole outline at once.

Common mistakes

• Rejecting a valid figure because it is rotated or partly overlapped by extra lines.
• Accepting a near match that has one connection in the wrong place.
• Mistaking a mirror image for a rotation.
• Following a visually similar outline while ignoring missing segments.
• Spending too long on one option instead of checking distinctive features systematically.

Quick revision summary

• Match the structure, not the size or screen position.
• A valid candidate can contain extra lines but cannot lose a required line.
• Rotation preserves handedness; reflection reverses it.
• Trace one distinctive feature and then verify every connection.
