A Euclidean shape

I had in mind the relationships between points, lines, angles, and shapes in Euclidean geometry.
A Euclidean shape is a two-dimensional or three-dimensional object that satisfies the postulates of Euclidean geometry.
These prototype sculptures refer to a three-dimensional art installation that can be displayed indoors or outdoors with the shape of a trapezoid.
The trapezoid is a two-dimensional geometric shape with four sides and precisely one pair of parallel sides.
These shapes are the building blocks of more complex geometric figures and describe the properties of objects and spaces.
