1. In mathematics and geometry, a point at infinity added to a projective space or geometric figure to complete it or satisfy certain properties.
In projective geometry, ideal points are used to ensure that parallel lines meet.
Em geometria projetiva, pontos ideais são usados para garantir que retas paralelas se encontrem.
2. In political science and economics, a hypothetical optimal outcome or position that represents the best possible solution according to specific criteria.
The ideal point of this voting model represents the most preferred policy position.
O ponto ideal deste modelo de votação representa a posição de política mais preferida.
3. In topology, a point added to a space to achieve desired topological properties.
Adding ideal points to the real line creates the extended real line.
