Square vs Trapezoid: Analyzing Geometric Shape Classification

To determine if a square is a trapezoid, we need to understand the definitions of both shapes:

• Definition of a Trapezoid: A trapezoid is a type of quadrilateral that has at least one pair of parallel sides.
• Definition of a Square: A square is a quadrilateral with four equal sides and four right angles, and it has two pairs of parallel sides (opposite sides are parallel).

Since a square has two pairs of parallel sides, it certainly has at least one pair of parallel sides, which satisfies the definition of a trapezoid under the inclusive definition.

Therefore, we conclude that a square is indeed a trapezoid.

The correct answer to the question is: Yes.
