We also include the statement and proof of a new result (Theorem 4.1) in linear algebra which is obviously fundamental to the geometrical investigation which constitutes the leit-motif of the paper.application/pdfpaper-foldingconstruction of quasi-regular polygonsstar polygonspractical geometrynumber theorylinear algebrafolyóiratcikkOpen AccessPeter Hilton and Jean Pedersenhttps://doi.org/10.5485/TMCS.2003.0001Teaching Mathematics and Computer Science11Teach.
