Question

5. What is the minimum number of unique
data required to draw a quadrilateral?​

Answer 1

Answer:

Quadrilateral has 10 elements (4 sides, 4 angles, 2 diagonals). We cannot draw a quadrilateral uniquely with 4 elements. We need at least 5 elements to draw unique quadrilaterals.

Answer 2

Answer:

a quadrilateral has 10 elements (4 sides, 4 angles and 2 diagonals) or measurements. To construct a unique quadrilateral we need to know 5 measurements (elements). Note: To construct a unique quadrilateral simply the knowledge of any five elements is not sufficient.

Five measurements can determine a quadrilateral uniquely. A quadrilateral can be constructed uniquely if the lengths of its four sides and a diagonal are given. A quadrilateral can be constructed uniquely if the lengths of its three sides and two diagonals are given.
