Deepa wants to construct quadrilateral ABCD given only AB = 5 cm, BC = 6 cm, CD = 4 cm and angle B = 100°. That is 4 measurements (3 sides + 1 angle). What is the minimum number of EXTRA measurements she must obtain to make the quadrilateral unique?

Question

Accepted Answer

1. A unique quadrilateral needs 5 measurements. Deepa has 4, so she needs 5 - 4 = 1 more measurement (e.g. side DA or angle C).

Deepa wants to construct quadrilateral ABCD given only AB = 5 cm, BC = 6 cm, CD = 4 cm and angle B = 100°.
That is 4 measurements (3 sides + 1 angle).
