Square : Pentagon :: ?

This question was previously asked in
RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)
The correct answer is
Triangle : Rhombus

Analyzing Polygon Relationships

The question requires identifying the relationship between 'Square' and 'Pentagon' and finding a similar relationship among the given options.

The Square-Pentagon Relationship

  • A Square is a polygon defined by having 4 sides.
  • A Pentagon is a polygon defined by having 5 sides.
  • The relationship is sequential based on the number of sides: A polygon with N sides is related to a polygon with N+1 sides. Here, N=4.

Evaluating Word Pairs

  1. Radius : Perimeter: This pair relates a component of a circle (Radius) to its boundary length (Perimeter). It doesn't involve the count of sides of polygons.
  2. Triangle : Rhombus:
    • A Triangle has 3 sides (N=3).
    • A Rhombus has 4 sides (N+1=4).
    This pair follows the N sides : N+1 sides pattern, matching the Square (4 sides) : Pentagon (5 sides) relationship.
  3. Side : Angle: These are fundamental elements of any polygon, not a sequential relationship based on the number of sides.
  4. Diagonal : Hypotenuse: These are specific types of lines within geometric figures. A hypotenuse relates specifically to right-angled triangles, and a diagonal relates to polygons generally. This pair doesn't fit the side-count progression.

Determining the Correct Match

The pair 'Triangle : Rhombus' exhibits the same core relationship (N sides : N+1 sides) as 'Square : Pentagon'.

Therefore, the correct answer is Option B.
