1. paiherea ngongo tapawha ko te wāhanga tapawha tuwhera ngongo tapawha maitai, hoki e mohiotia ana kowhao maitai matao-hanga.He mea hanga na roto i te piko makariri me te weriweri auau teitei i muri i te wera-hurihia, te makariri-hurihia ranei i te takai, i te porowhita ranei hei patea te rino Hanga me te ahua tapawha tapawha me te rahi.
I tua atu i te matotoru o te matotoru o te pakitara o te ngongo tapawha matotoru-taiepa, ko te rahi o te kokonga me te papatahi o te taha ka eke ki runga ake ranei i te taumata o te parenga o te ngongo tapawha hanga makariri.Ko te rahi o te koki R kei waenga i te 2 nga wa me te 3 nga wa te matotoru o te pakitara..E ai ki nga hiahia o nga kaihoko, ka taea ano e matou te whakaputa i nga ngongo tapawha R-koki o te rahi e hiahiatia ana e nga kaihoko;
2. Ngongo tapawha Ko te ngongo tapawha tuitui he takai maitai roa me te wahanga tuwhera, kaore he hononga ki te taha.He ngongo tapawha i hangaia ma te whakaputa i te ngongo korekore ki nga taha e 4 o te pokepokea ai.He wahanga tuwhera te ngongo tapawha, he nui te whakamahi.Kei te whakamahia i roto i te kawe wai, te tautoko waipēhi, te hanganga miihini, te reo me te iti o te pehanga, te ngongo kohua teitei, te ngongo whakawhiti wera, te hau, te hinu me etahi atu ahumahi.He kaha ake i te paiherea, e kore e pakaru.
