Numbering starts from the leftmost figure.
1) Opposite sides are equal $\implies$ quadrilateral is a parallelogram. (Can be proven using basic congruency theorems)
2)
Opposite sides are parallel $\implies$ trapezium.
But the other pair of sides are not parallel, hence in the general case this is not a parallelogram but is a trapezium with two equal sides.
3) One pair of opposite sides are congruent <em>and</em><em> </em>parallel $\implies$ this is a parallelogram.
Proof: Join two vertices and you get that the two triangles formed are congruent.
4)
Diagonals are bisected at their intersections $\implies$ Quadrilateral is a parallelogram.
Show that the two opposite little triangles are congruent by using SAS test (or whatever you call it)
So the figure which is not a parallelogram is 2.

Answer:
A
Step-by-step explanation:
The two triangles are congruent because every corresponding side has the same length, & every corresponding angle has the same measure. In short she's correct

Step-by-step explanation:

Not only do they handle the day-to-day tasks of selling, they also think of the big picture and make decisions that will get the company to where it wants to go. This is called strategic decision making, where decisions are made according to a company's goals or mission. This type of decision making guides the choices that are made, aligning them with the company objectives.
