What is a pentamonio?

Answer 1

A pentamonio is a type of geometric figure made up of five connected squares, resembling a form of polyomino. It is a specific case of a polyomino, which is a plane geometric figure formed by joining one or more equal squares edge to edge. Pentominoes can take various shapes, and they are commonly used in mathematical puzzles and games, such as Tetris. Each unique arrangement of five squares can be rotated and reflected, leading to a total of 12 distinct pentomino shapes.
