Classify two-dimensional figures

Sort four-sided shapes by their most exact name: square, rectangle, rhombus, parallelogram or trapezoid.

Sort

What is the most exact name for the four-sided shape?
Tap a card, then tap its group.

Assumptions

•
A trapezoid has at least one pair of parallel sides, so every parallelogram is a trapezoid too.
•
A parallelogram has two pairs of parallel sides. A rectangle is a parallelogram with four right angles. A rhombus has four equal sides.
•
A square is both: four right angles and four equal sides. Give the most exact name.
•
Some books say a trapezoid has exactly one pair. Then a parallelogram is not a trapezoid.
