Question

What would be the general formula of number of details to be known, for constructing a quadrilateral?

(a) (n-1)… where n is the number of sides

(b) (n+1)… where n is the number of sides

(c) (n×2)… where n is the number of sides

(d) (n/2)… where n is the number of sides

This question was posed to me at a job interview.

I would like to ask this question from Geometry topic in division Practical Geometry of Mathematics – Class 8

Answer 1

Right choice is (b) (n+1)… where n is the number of sides

The best explanation: If one wishes to construct a unique quadrilateral, the requirement is (n+1) number of details. If any student has n number of details, the constructed quadrilateral would not be a unique quadrilateral.
