same cardboard stock as shims 80 of fig8 it will fit securely into the gap in the center of a side of the polygon u201c sandwich u201d depicted in fig7 and 8 a cardboard connecting strip 90 thus provides in a rudimentary fashion the basic functionality of a tab 30 cardboard strip 90 has been folded lengthwise thereby weakening the cardboard at the fold it will consequently provide a hinging action at the fold cardboard strips 90 will align the sides of the polygons that they connect ensuring that said sides meet parallel at an edge without cardboard strips 90 there is nothing to prevent the sides of the polygons from skewing or misaligning cardboard strips 90 would permit multiple polygons to be connected making them easier to align and thus making it far easier to fit said polygons together into polyhedra cardboard strips 90 would provide a good deal of structural support allowing a polyhedron to be stabilized by using a minimal amount of tape because the edges of the polyhedron would not be permanently fused or adhered the polyhedron could be disassembled into component polygons u2014 by cutting the tape that holds it together if necessary fig1 depicts an equilateral triangle object 10 that has been provided with slots in.
