Question

A square can also be classified as which of the following?

Select all that apply.

quadrilateral
parallelogram
rectangle
trapezoid
rhombus

Answer 1

Select: quadrilateral, parallelogram, rectangle, rhombus.

Why:
- Square has four sides → quadrilateral.
- Opposite sides parallel → parallelogram.
- All angles 90° → rectangle.
- All sides equal → rhombus.

Note: Whether a square is a trapezoid depends on definition. Under the common exclusive definition ("exactly one pair of parallel sides") it is not; under the inclusive definition ("at least one pair of parallel sides") it would be.
