Quadrilaterals
A quadrilateral is a polygon with 4 sides. Thus the figure is a quadrilateral.
A parallelogram is a quadrilateral with two pairs of parallel sides. There is no clear indication if the opposite sides are parallel, but we'll assume it anyway.
A rhombus is a parallelogram with four congruent sides. It's clear that not all the sides have the same length, thus it's not a rhombus.
A square is a parallelogram with four congruent sides and four right angles. The figure is clearly not a square.
A trapezoid has exactly one pair of parallel sides. Since we have already assumed it's a parallelogram, then it cannot be a trapezoid.
Correct choices to select:
A. quadrilateral
B. parallelogram (assumed)
