Question

to construct a quadrilateral uniquely, ............................ independent elements must be known..(fill in the blanks)​

Answer 1

Answer:

If the quadrilateral is irregular i.e it is not a rhombus or a parallelogram, then we need to know the lengths of all four sides plus one diagonal (i.e. at least five parts).

Example: For a quadrilateral ABCD, if we know AB=a,BC=b,CD=c,DA=d and AC=k then we can construct the unique parallelogram subjected that

a+b>k and c+d>k.

In fact we would construct two triangles △ABC and △ADC on common base AC, apexes B and D being on either side of AC, using SSS method
