With the following data, a quadrilateral can be constructed. PQ = 4 cm, QR = 6 cm, RS = 5 cm, PS = 5.5 cm and PR = 7 cm.
True
The diagonal PR is a part of 2 triangles PSR and PQR.
Since one side of a triangle cannot be greater than the sum of other 2 sides, the length of PR must be smaller than sums PS +SR and PQ+QR.
In this quadrilateral, the condition is satisfied.
