Either diagonal of a rhombus divides it into two congruent isosceles triangles. Stimuli in Stroop paradigms can be divided into 3 groups&colon; neutral, congruent and incongruent. Targets were flanked by either a congruent or an incongruent set of letters. Triangles with three equal angles (AAA) are similar, but not necessarily congruent. The same odd numbers are now arranged in two different ways in congruent triangles. Infants looked longer at incongruent pairings than at congruent pairings. The rhombic dodecahedron is a convex polyhedron with 12 congruent rhombi as its faces. This will use the theory of congruent triangles. Therefore, the triangles and are congruent by SAS. Polyhedra with congruent regular faces of six or more sides are all non-convex. This is equivalent to the tiling being an edge-to-edge tiling by congruent regular polygons. The gyroid separates space into two oppositely congruent labyrinths of passages. There are also tilings by congruent polyaboloes. The goal is to have the two concepts of self become congruent. The rhombic icosahedron is a zonohedron made up of 20 congruent rhombs.
