Question

Five diagrams \(A, B, C, D,\) and \(E\) are given. Three out of these, when put together, form a square. Identify the correct set of diagrams.

• A. \(A, C, D\)
• B. \(B, C, D\)
• C. \(A, B, C\)
• D. \(C, D, E\)

Hint:

In such puzzles, always focus on the outer boundary first—if it cannot become a perfect square, the combination is incorrect.

Answer 1

The Correct Option is B

To solve this problem, we need to identify which set of three diagrams can be combined to form a perfect square. Let's examine each option to determine the correct set.

1. Observe the shapes of diagrams \(B, C,\) and \(D\) in the image. These diagrams have edges and segments that can seamlessly fit into each other.
2. Diagram \(B\) provides a horizontal base with a notch that fits with diagram \(C\).
3. Diagram \(D\), which has an L-shape, can fit on top of or beside the combined forms of \(B\) and \(C\), covering all empty spaces to form a complete square.
4. Check the fit by aligning the edges of diagrams \(B\), \(C\), and \(D\), and notice they together complete a square without any protrusion or gap. None of the other options (sets) align perfectly.

Conclusion: The correct set of diagrams that when combined form a square is B, C, D.
