Progression des Formes

Apprendre

Comment les formes changent ou restent constantes dans les lignes et colonnes d'une matrice.

Shape rules determine which geometric form appears in each cell. The simplest rule is 'constant shape' where all cells contain the same form. Progression rules change the shape systematically—either the same order repeats in each row, each column has its own shape, or each row/column contains three different shapes. Understanding shape rules helps isolate this attribute from size and fill.

shape(cell) = f(row, col) or constant

• Constant: All cells contain circles
• Row pattern: Each row shows circle → square → triangle
• All different: Each row has 3 unique shapes (order may vary)

Comment le reconnaître

• Check if all shapes are identical (constant rule)
• Compare shapes across each row—do they follow a pattern?
• Compare shapes down each column—do they follow a pattern?
• Note: shape is independent of size and fill
