. How many measurements can determine a quadrilateral uniquely
- 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.
Option D is correct, that is,
5 measurements can determine a quadrilateral uniquely.
