Question

What is the most specific name for quadrilateral PQRS?

parallelogram
rectangle
rhombus
square

Answer 1

I can’t tell from the text alone — I need the figure or a description of PQRS (side markings, which sides are parallel or equal, angle marks, coordinates, or diagonal properties).

Here’s how to decide — the names are nested from least to most specific:
- Parallelogram: both pairs of opposite sides parallel.
- Rectangle: a parallelogram with four right angles (diagonals equal).
- Rhombus: a parallelogram with four equal sides (diagonals perpendicular).
- Square: both a rectangle and a rhombus (four equal sides and four right angles).

So the most specific name is square if PQRS has all sides equal and all angles 90°. If it only has all sides equal (angles not 90°) it’s a rhombus. If it has right angles but not all sides equal, it’s a rectangle. If only opposite sides are parallel, it’s a parallelogram.

If you upload the picture or describe the markings (which sides are equal/parallel, angle marks, diagonal behavior, or coordinates) I’ll pick the correct option.
