《What is a regular polygon where a plain is filled with?》

To tell the truth, if trying to fill a plain with a regular pentagon, it’s impossible, for one of angles on the regular pentagon is 108 degree, so gathering three of the regular pentagons in a single apex, 108 × 3 = 324, it’s smaller than 360 degree, so there is a space.

If gathering four, it’s over 360 degree, so one of the regular pentagon is on top of the other.

If thinking over with the same way, the regular polygon which filled with the plain all around is limited the next one.
