How many measurements are required to construct a quadrilateral, uniquely? |
Four Five Six Three |
Five |
A quadrilateral can be formed uniquely if know the length of the 4 sides and length of its diagonal. Also, we can form a diagonal if we know the length of any 3 sides plus length of 2 diagonals. Thus, in any case at least 5 measurements must be known. |
