Solution
The correct option is D Altitude AE of ABCD To construct a trapezium, we need four independent measurements to construct a trapezium.
A trapezium can be uniquely constructed given the following measurements:
1) three sides and one diagonal
2) three sides and one angle
3) two sides and two angles
4) four sides
AD is the fourth side of the trapezium, DB is the diagonal and ∠ABC is an angle of the trapezium.
Thus, these are the correct options.
