Ma kēia paʻi ʻana, e noʻonoʻo mākou i ke ʻano o ke kihi kūpono, e papa inoa i nā ʻano geometric koʻikoʻi i loaʻa ai ia, a e nānā pū i kahi laʻana o kahi pilikia ma kēia kumuhana.
Ka wehewehe ʻana o kahi kihi ʻākau
ʻO ka angle kauohaina ua like ia me 90 degere.
I nā kaha kiʻi, ʻaʻole i hoʻohana ʻia kahi arc poepoe e hōʻike i kēlā ʻano kihi, akā he huinahā.
He hapalua ka huina pololei (180°) a ma na radiana, ua like ia me Π / 2.
Nā ʻano me nā kihi ʻākau
1. Pāhāhā – he rhombus, ua like nā kihi a pau me 90 °.
2. Rectangle – he parallelogram, pololei no hoi na kihi a pau.
3. O ka huinakolu kupono kekahi o kona mau huina kupono.
4. Trapezoid rectangular - ma kahi o hoʻokahi o nā kihi he 90 °.
Laʻana o kahi pilikia
Ua ikeia ma ka huinakolu, ua pololei kekahi o na huina, a ua like na huina elua me kekahi. E ʻimi kākou i nā waiwai ʻike ʻole.
pāʻoihana
E like me kā mākou ʻike mai , ua like ia me 180°.
No laila, ʻelua huina ʻike ʻole ʻia he 90°
