. How many measurements can determine a quadrilateral uniquely


A: 2

B: 3

C: 4

D: 5

Best Answer

Explanation:

  • A quadrilateral is a structure that has 4 or more sides.
  •  A quadrilateral can possibly be constructed uniquely when the lengths of its four sides and one of its diagonals are given. 
  • Or a quadrilateral can be constructed uniquely if the lengths of its three sides and two diagonals are given.
  • Hence, five measurements are required to construct a quadrilateral uniquely.

Final answer:

Option D is correct, that is,

5 measurements can determine a quadrilateral uniquely.
