Dodecahedron a Origami dabara

Module Origami - mai kyau tushen ga dodecahedron. Yadda za a yi dodecahedron daga wata takarda a wani ire dabara? 30 Za bukatar wani rectangular ko square takardu. Kowace daga cikin leaflets folded a cikin rabin, to, kõwane rabin tanƙwara a gaban shugabanci - shi so "akordiyon" a hudu tarawa. Wani lokaci, idan takardar ba square, yin "harmonica" a uku na Bugu da kari. A sakamakon kana da a cikin hannãyenku daga kunkuntar tsiri na promougolnaya. Sa'an nan kuma, a kan kowane gefe na murabba'i mai dari tare da kunkuntar gefe na flexing yankin. Sasanninta aka kafa a daya shugabanci - nan gaba na fastening da za a refueled a cikin "harmonica". Sa'an nan tanƙwara module baƙin slant diagonally daga sasanninta na kananan gefe. Saboda haka, daya module Origami dodecahedron - wani uku-girma, shi ya hada biyu gefuna da sasanninta na adadi na nan gaba. Sa'ad da dukan kayayyaki suna shirye, za ka iya fara taro.

A taron jama'a farawa da guda kumburi ga wanda ka so su dauki uku kayayyaki. A adadi a kasa ne a blue, da ruwan hoda da kuma rawaya Origami ins. Majalisar zane-zane ne fairly sauki, da kuma irin wannan adadi iya rike ko da novice.
