Question

The number of parameters required to construct a quadrilateral is ___. Choose the most appropriate answer to fill in the blank.

• A. 5
• B. 4
• C. 3
• D. 2

Answer 1

The correct option is A

5

A quadrilateral has ten parts in all: four sides, four angles and two diagonals.
The possible cases in which quadrilaterals can be constructed are:-

• Construction of quadrilaterals when four sides and one diagonal are given.
• Construction of quadrilaterals when three sides and two diagonals are given.
• Construction of quadrilaterals when three sides and two included angles are given.
• Construction of quadrilaterals when two adjacent sides and three angles are given.
• Construction of quadrilaterals when four sides and one angle are given.

All these cases require a minimum of five parameters.
