To find the value of m<DAB in question 1, we know that opposite angles in a parallelogram are congruent. Thus, m<DAB = m<CDA = 128°.
To find AE in question 2, we can use the fact that opposite sides in a parallelogram are congruent. Since AC is a diagonal and it is congruent to BD, we have BD = AC = 18. So, AE = AC - CE = 18 - 6 = 12.
For question 3, based on the information in the diagram, we can prove that the figure is a parallelogram because both pairs of opposite sides are congruent.
In question 4, we don't have enough information to find the exact values of x and y in the trapezoid ABCD.
