a rhombus is a parallelogram so I'm just using the same example for both

# data[].attributes.body
a four-sided plane rectilinear figure with opposite sides parallel.

# data[].attributes.body
a parallelogram with opposite equal acute angles, opposite equal obtuse angles, and four equal sides.

# data[].attributes.body
a plane figure with three straight sides and three angles.

# data[].attributes.body
a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length).

# data[].attributes.body
a quadrilateral with only one pair of parallel sides.

# data[].attributes.body
A quadrilateral with adjacent sides perpendicular (all four angles are therefore right angles).

# data[].attributes.body
A quadrilateral with four right angles and all four sides of equal length.

Area = Base * Height

# data[].attributes.body
A quadrilateral with two pairs of distinct adjacent sides equal in length.

# data[].attributes.body
Area = Base * Height
