What do jigsaw puzzle pieces look like?

Jigsaw puzzle pieces are typically made of cardboard or plastic and come in a variety of shapes and sizes.

General Features:

* Irregular Shape: Each piece has a unique, irregular shape with a combination of straight and curved edges.

* Interlocking Tabs and Grooves: Pieces fit together through a system of interlocking tabs and grooves, creating a tight and secure fit.

* Image Fragment: Each piece features a portion of the overall picture, forming a complete image when all pieces are assembled.

* Piece Size: Pieces can range from very small to large, depending on the difficulty level of the puzzle.

Specific Shapes:

* Edge Pieces: Pieces that form the outer edges of the puzzle, usually with a straight edge on one side and an irregular edge on the other.

* Corner Pieces: Pieces with two straight edges that meet at a right angle.

* Inner Pieces: Pieces that fit within the interior of the puzzle, usually with irregular shapes on all sides.

Variations:

* Different Materials: Some puzzles are made of wood, metal, or even glass.

* 3D Puzzles: Some puzzles form a three-dimensional object instead of a flat image.

* Unique Shapes: Some puzzles use unusual or unconventional shapes, such as animals, objects, or abstract designs.

Ultimately, the appearance of jigsaw puzzle pieces varies greatly depending on the specific puzzle, but they all share the fundamental characteristic of interlocking to form a larger image.
