The square and the parralalagram.
In a tangram, you can create various quadrilaterals using different combinations of its seven pieces. The specific number of distinct quadrilaterals depends on how you define them (e.g., congruent shapes or different orientations). Generally, using just two pieces, you can form at least a few basic quadrilaterals, such as rectangles or parallelograms, but the total combinations can be quite numerous depending on the arrangements. Overall, the creativity in combining the pieces can lead to a wide variety of quadrilateral shapes.
You cannot have a 2 piece tangram. A tangram, by definition, is 7 pieces.

Trapezoids make up the set of quadrilaterals with 2 pairs of parallel sides.

Quadrilaterals are two-dimensional shapes that have four sides. Quadrilaterals that have only one set of parallel sides are called trapezoids.

It's not possible!
Without the triangles of a tangram all that is left is the parallelogram and the small square. So using only the small square yes (the small square itself), otherwise with the square and the parallelogram from a tangram no.
