Embedded Figures is a critical non-verbal reasoning topic in SOF NSO that tests your spatial visualization and pattern recognition abilities. In these questions, you are shown a simple figure (the "embedded" or "hidden" figure) and then a complex figure. Your task is to identify whether the simple figure is hidden somewhere within the complex figure, and if so, where it appears.
Key ideas
- Simple Figure: The target shape you must find—typically a geometric form like a triangle, square, circle, arrow, or letter. This figure is always shown clearly and separately.
- Complex Figure: A busy diagram containing many overlapping lines, shapes, and patterns. The simple figure is hidden somewhere within this visual clutter, maintaining its exact shape and proportions.
- Exact Match Required: The embedded figure must have the same shape, angles, and proportions as the simple figure. A similar but not identical shape is incorrect. Rotations are generally not allowed unless specified.
- No Overlapping Rule: In most SOF NSO questions, the embedded figure's outline should not share lines with other shapes—it should be traceable as a distinct, complete figure within the complex diagram.
- Systematic Scanning: Successful solvers mentally divide the complex figure into zones (top-left, top-right, center, etc.) and check each systematically rather than looking randomly.
Watch out for
- Hasty Visual Matching → Careful Angle Verification: Students often pick the first shape that "looks close" to the simple figure without verifying all angles and side lengths. Fix: Mentally measure each side and angle against the original.
- Ignoring Orientation → Check Upright vs Rotated: Assuming the embedded figure can be rotated when the question doesn't allow it. Fix: Always verify that the figure's orientation exactly matches the simple figure unless rotation is explicitly permitted.
- Tracing Shared Boundaries → Seeking Distinct Outlines: Trying to use lines that are already part of other shapes' boundaries, creating ambiguous overlaps. Fix: The embedded figure should be traceable as a standalone shape with its own complete perimeter, even if surrounded by other elements.
Quick reference
- Scan systematically: Divide complex figure into zones, check each methodically rather than randomly.
- Trace mentally: If you can trace the simple figure's complete outline without interruption, you've found it.
- Size and orientation match exactly: No rotation, reflection, or scaling unless stated otherwise.
- Exact shape required: Similar is not sufficient—every angle and side length must match.
- Check edges and corners first: Embedded figures often appear at boundaries or in the center of complex figures.
Check yourself: 3 questions
1. A square is divided into four equal parts by two perpendicular lines meeting at the center. Which of the following figures is definitely embedded in this design? (Imagine a square with a vertical line and a horizontal line crossing at the center, dividing it into 4 equal squares)
2. A complex figure contains multiple overlapping triangles forming a star pattern. How many distinct triangles can be identified in a figure where a large triangle has three lines drawn from each vertex to the midpoint of the opposite side? (The three medians divide the triangle into smaller regions)
3. In a rectangular grid of 3 rows and 3 columns (making 9 small squares), all horizontal and vertical lines are drawn. Which shape is NOT embedded in this grid?
