Ko te mata rara 2+2 me te awaawa ngira o te rango ngira ka whakaritea kia rerekē. Ina whakaritea te pereti ngira me te oko ngira, ka kumea te ngira kotahi i ia ngira e rua, nō te kiko rara momo kumea ngira tēnei. He maha ngā kōhao ka puta i te wā whakaputa. Haunga ngā tikanga whakatikatika whānui, i te wā e whatu ana i tēnei momo hanganga rara, me iti te tawhiti i waenga i ngā waha rango. Ko te kaupapa he whakaiti i te roa o te pewa whakatau ka hangaia i te wā e whatuhia ana te ngira mata me te ngira rango.

Kei te Pikitia 1 te hoahoa kauwhata o te hanganga koiri. Nā te mea ko te rahi o L te mea e whakatau tika ana i te tohatoha o ngā koropiko, ko tana mahi anō he whakaputa i te taipana nā te tukunga o te miro o tēnei wāhanga miro, e kukume ana i te koropiko a me te koropiko b kia piri tahi, ka kati, ka taupatupatu tetahi ki tetahi hei hanga i tētahi momo papanga ahurei. Mō te āhuatanga kōhao, he mea nui te rahi o L. Nā te mea i roto i te take o te roa raina kotahi, ko te roa o te L, ko te iti ake o te roa o te miro e nohoia ana e ngā koropiko a me b, ā, ko te iti ake o ngā koropiko e hangaia ana; ā, ko te poto o te L, ko te roa ake o te miro e nohoia ana e ngā koropiko a me b. He nui ake hoki te koiri.

Ngā take mō te hanganga o ngā kōhao me ngā otinga motuhake

1. Ko te take matua mō te hanganga o ngā kōhao he kaha e nui ake ana i tōna ake kaha whati i te wā e raranga ana te miro.Ka taea te whakaputa i tēnei kaha i te wā e whāngai ana i te miro (he nui rawa te kume o te whāngai miro), tērā pea nā te hohonutanga piko rawa, tērā pea nā te tata rawa o te taura maitai me te ngira whatu, ka taea e koe te whakarite i te piko o te miro kia ea ai te hohonutanga me te tūranga o te taura maitai.

2. Ko tētahi atu pea, kāore e taea te tango katoa i te koropiko tawhito mai i te ngira i muri i te wetewete i te koropiko nā te iti rawa o te kume o te takai, te iti rawa rānei o te hohonutanga piko o te pereti ngira.Ina hikitia anō te ngira whatu, ka whati te koropiko tawhito. Ka taea hoki tēnei te whakatau mā te whakarerekē i te kaha o te hurihuri, te hohonu rānei o te piko. Ko tētahi atu pea ko te iti rawa o te miro e mau ana i te ngira whatu (arā, he matotoru rawa te kakahu, ā, he poto rawa te roa o te miro), ka hua ake he iti rawa te roa o te koropiko, he iti iho i te porowhita o te ngira, ā, ka wetekina, ka wetekina rānei te koropiko. Ka puta te uauatanga ina whati te ngira. Ka taea tēnei te whakatau mā te whakanui ake i te nui o te miro e whāngaihia ana.

3. Ko te tuatoru o ngā āhuatanga, ina he noa te nui o te miro e whāngai ana, he roa rawa te miro wāhanga-L nā te waha rango teitei, ā, he iti rawa ngā koropiko a me b, ka uaua ai te wetewete me te motu i te koropiko, ā, i te mutunga ka motu. I tēnei wā, me whakaiti. Ka whakaitihia te teitei o te mata me te tawhiti i waenganui i ngā waha rango hei whakaoti i te raruraru.

Ina whakamahia e te mīhini whatu rara te whatu pou-tūnga, he iti rawa te koropiko, ā, he maha ngā wā ka whati ina hoki whakamuri te koropiko. Nā te mea i tēnei tūranga, ka hoki whakamuri te ngira porowhita me te ngira rango i te wā kotahi, he nui ake te roa o te koropiko i te roa o te koropiko e hiahiatia ana ina tukuna te koropiko. Ina wetewetehia te koropiko i ia taahiraa, ka taka tuatahi ngā ngira whatu porowhita ngira i te koropiko, kātahi ka taka te pereti ngira i te koropiko. Nā te whakawhiti koiri, kāore e hiahiatia he roa koiri nui i te wā e wetewetehia ana. Ina whakamahi i te whatu tū-whakamuri, ina he iti rawa te koropiko, he maha ngā wā ka whati te koropiko ina wetewetehia. Nā te mea ka tangohia te koropiko tawhito i te wā kotahi i runga i te ngira porowhita me te ngira o te oko ina whakaritea te tūranga, ahakoa ka mahia hoki te wetewete i te wā kotahi, nā te mea he nui ake te porowhita o te ngira (ina kati te ngira) i te porowhita o te wāhanga pine ngira, Nō reira, he roa ake te roa o te koiri e hiahiatia ana mō te wetewete i te wā e wetewetehia ana.

I roto i te mahi hanga tūturu, ki te whakamahia te whatu pou-tūnga noa, arā, ka piko ngā ngira o te rango i mua i ngā ngira o te mata, ka kitea te āhua o te papanga he piri, he mārama hoki i roto i ngā koropiko rango, engari he wetekina ngā koropiko o te mata. He nui te tawhiti o ngā rārangi roa i ngā taha e rua o te papanga, he whānui ake te whānui o te papanga, ā, he ngoikore te ngāwari o te papanga. Ko te take o ēnei āhuatanga ko te tūranga whanaunga o te kāme mata me te kāme mata o te rango ngira. I te whakamahi i te whatu i muri i te kai, ka tukuna tuatahitia te ngira o te rango ngira, ā, ka wetekina rawatia te koropiko i tangohia i muri i te tango i te whānui o te ngira o te rango ngira. E rua noa iho ngā miro hou kua whāngaihia i roto i te koropiko, engari i tēnei wā ka wetekina te mata. I te tīmatanga o te ngira ki te wetewete, ka totoro te koropiko tawhito e te ngira o te ngira mata, ā, ka piri. I tēnei wā, kua oti noa te wetekina o te koropiko tawhito o te rango ngira, ā, ka wetekina rawatia. Nā te mea he miro kotahi ngā tuitui tawhito o te ngira mata me ngā tuitui tawhito o te rango ngira, ka whakawhitihia e ngā tuitui tawhito o ngā ngira rango ngira wetekina tētahi wāhanga o te miro ki ngā tuitui tawhito o ngā ngira mata piri hei āwhina i ngā ngira tawhito o te ngira mata. Ka wetekina mārire te koiri.

Nā te whakawhiti o te miro, ka piri ngā koropiko tawhito o te ngira rango ngira wetekina kua wetekina, ā, ka wetekina ngā koropiko tawhito o te ngira mata piri tuatahi, kia maeneene ai te wetekina. Ina wetekina te ngira mata, ā, kua wetekina te ngira rango, ka piri tonu ngā koropiko tawhito kua piri nā te whakawhiti koropiko, ā, ka wetekina tonu ngā koropiko tawhito o te ngira mata kua wetekina nā te whakawhiti koropiko i muri i te otinga o te wetekina. Mena kāore he mahi kē atu a te ngira rango me te ngira mata i muri i te otinga o te mahi wetekina, ā, ka uru tika ki te tukanga whatu e whai ake nei, ka kore e taea te huri i te whakawhiti tuitui e puta ana i te tukanga wetekina, ka hua ake te hanganga o te tukanga whatu i muri i te whatu. He wetekina te taha o muri o te kakahu, ā, he piri te taha o mua, koia te take i nui ake ai te tawhiti me te whānui o ngā rārangi.
