Forming a regular pentagon, decagon and pentagram using origami technique is based on the construction of approximately 36oangle by dint of A4 paper of format. The implemented method is “fold and cut”. We endeavored to obtain the polygons with the most accurate sides, i.e. with the minimal aberration of the interior angle. There is also considered an ideal paper format, which would provide the most accurate result, with negligible error. As the most suitable, we accepted the argentic rectangle.
