Figure Classification and Embedded Figures

Grouping figures by shared visual properties, and locating a smaller given figure hidden within a larger, more complex diagram.

📖 ~11 min read 🧩 SSC Reasoning

Introduction

Figure Classification asks you to group figures by a shared visual property (like Chapter 2's word classification, but for shapes); Embedded Figures asks you to locate a smaller given shape hidden inside a more complex, larger figure.

Figure Classification — What to Check

Property to CheckExample
Number of sidesThree figures are quadrilaterals, one is a pentagon
Number of lines/curvesThree figures made of 3 straight lines, one has a curve
SymmetryThree figures symmetric, one asymmetric
Shading/patternThree figures shaded on the same side, one shaded differently
Rotation relationshipThree figures are rotations of each other, one is a mirror image (not a rotation)
Diagram — Figures That Are Rotations vs a Mirror Image (Odd One Out)
Original Rotated 120° Rotated 240° Mirror (odd one)

The first three triangles are the same figure rotated by different angles; the fourth is a mirror-flipped version — a mirror image is NOT a rotation, making it the odd one out.

Embedded Figures — Search Strategy

Flowchart — Finding an Embedded Figure
Study the smaller given figure carefully — note its exact shape, number of sides, and any distinctive angle
↓
Scan the larger figure systematically (left to right, top to bottom) for that exact outline, ignoring extra overlapping lines
↓
Trace the matching lines mentally (or lightly with a pencil in practice) to confirm the shape is fully present, not just partially similar
Diagram — A Triangle Embedded Within a Complex Figure

The target triangle (red dashed outline) is hidden among the overlapping lines of the larger composite figure.

💡 Exam Tip: In Embedded Figures, focus first on any unusual angle or distinctive vertex in the small figure — it's much faster to locate one unique angle in the large figure and then verify the rest of the shape around it, than to try matching the whole outline at once.
✅ Practice Focus: Rotation vs mirror-image distinction (mirror is never a valid rotation) · Systematic property-checking for figure classification · Anchor-point search strategy for embedded figures.
