Question

Select the alternative which represents three out of the five alternative figures which when fitted into each other would form a complete square. 

• A. 1,2,4
• B. 3,4,5
• C. 1,2,3
• D. 1,3,5
• E. 5,2,4

Hint:

For figure fitting:
• Look for right angles first.
• Try to visualize outer boundary (square edges).
• Eliminate sets that leave gaps or overlaps.

Answer 1

The Correct Option is D

Concept: This is a figure fitting (assembly) problem:
• Pieces must combine to form a perfect square.
• Edges should align without gaps or overlaps.
• Angles must complement each other (sum to $90^\circ$ or $180^\circ$ where needed).
Step 1: Observe given figures.
• (1) and (2): Irregular angled shapes.
• (3): Quadrilateral-like piece.
• (4): Small square.
• (5): Right-angled triangular shape.

Step 2: Check possible combinations.
• We need pieces that can:
• Form straight boundaries
• Fill all corners of a square

Step 3: Analyze valid set.
• Figure (5) provides a right angle → useful for square corner.
• Figure (3) fills central/side portion.
• Figure (1) complements remaining shape.

Step 4: Eliminate others.
• Sets with (4) leave gaps due to small size.
• Other combinations cannot form perfect square boundary.

Step 5: Conclusion.
Answer = 1,3,5
