ʻOkoʻa ma waena o concave a me convex

Hō'ike

I ke ao nei I loko o ka geometry, ʻelua mau huaʻōlelo i huikau kekahi me kekahi: concave a me convex. I ka nānā mua ʻana, ʻano like paha nā mea convex a me concave, akā he mau ʻano ʻokoʻa ko lākou e hoʻokaʻawale iā lākou. Ma kēia ʻatikala e ʻimi hohonu mākou i nā ʻokoʻa ma waena o kēia mau huaʻōlelo ʻelua.

He aha ka convex?

E hoʻomaka kākou ma ka wehewehe ʻana i ke ʻano o ka mea convex. ʻO ka mea convex kekahi mea e huli ana nā kihi a pau i waho, ʻo ia hoʻi, ʻaʻohe ʻaoʻao concave a i loko. Hiki iā ʻoe ke ʻike maʻalahi i kahi mea convex inā hiki iā ʻoe ke hoʻohui i nā helu ʻelua i loko o ka mea me kahi laina pololei ʻaʻole e haʻalele i ka mea i kēlā me kēia manawa.

Nā laʻana o nā mea convex

• He pōʻai
• He pahu
• he cone
• he poepoe

He aha ka concave?

I kēia manawa, e kamaʻilio kākou e pili ana i nā mea concave. ʻO ka mea concave he mea nona ka liʻiliʻi hoʻokahi kihi e kū ana i loko, ʻo ia hoʻi, he mau ʻaoʻao i ʻōpiʻo a i ʻole concave i loko. Inā hoʻāʻo ʻoe e hoʻohui i ʻelua mau kiko i loko o ka mea me kahi laina pololei, e hele kēia laina i waho o ka mea a hoʻi i loko.

Nā laʻana o nā mea concave

• He hoolele
• he pola hohonu
• he noho lio
• ʻO kahi ʻoki ʻokiʻoki

He aha ka ʻokoʻa?

ʻO ka ʻokoʻa nui ma waena o nā mea convex a me nā mea concave ʻo ke ʻano o ka ʻike ʻana o ka mālamalama iā lākou. I loko o kahi mea convex, e ʻike mau ʻia ka mālamalama i waho, ʻo ia hoʻi E ʻike mau ʻia ka mea mai kēlā me kēia kihi. Ma ka ʻaoʻao ʻē aʻe, i loko o kahi mea concave, e hoʻomālamalama ka mālamalama i loko, ʻo ia hiki iā ia ke hana e hoemi i ka ikeia o ka mea mai kekahi mau kihi.

ʻAʻohe

I ka pōkole, ʻo nā mea convex ko lākou mau kihi āpau e huli ana i waho, ʻoiai ʻo nā mea concave aia ma kahi o hoʻokahi kihi e kū ana i loko. ʻO ka ʻokoʻa nui ma waena o kēia mau huaʻōlelo ʻelua, ʻo ia ke ʻano o ka ʻike ʻana o ka mālamalama iā lākou a pehea e pili ai i ko lākou ʻike. Manaʻo mākou ua kōkua kēia ʻatikala e wehewehe i nā ʻokoʻa ma waena o kēia mau huaʻōlelo ʻelua a hiki iā ʻoe ke hoʻomaopopo maikaʻi i ka geometry.
