Prism Properties

A yoo ṣe akiyesi awọn ohun-ini nipa lilo apẹẹrẹ ti prism taara hexagonal, ṣugbọn wọn wulo fun eyikeyi iru eeya miiran.

Ohun-ini 1

Prism kan ni awọn ipilẹ dogba meji, eyiti o jẹ polygons.

Awon. ABCDEF = A₁B₁C₁D₁E₁F₁

Ohun-ini 2

Awọn oju ẹgbẹ ti eyikeyi prism jẹ parallelograms.

Ninu aworan loke o jẹ: AA₁B₁B, BB₁C₁C, CC₁D₁D, DD₁E₁E, EE₁F₁F и AA₁F₁F.

Ohun-ini 3

Gbogbo awọn egbegbe ẹgbẹ ti prism jẹ afiwera ati dọgba.

• AA₁ = BB₁ = CC₁ = DD₁ = EE₁ = FF₁
• AA₁ || BB₁ || CC₁ || DD₁ || EE₁ || FF₁

Ohun-ini 4

Abala papẹndikula ti prism wa ni awọn igun ọtun si gbogbo awọn oju ẹgbẹ ati awọn egbegbe ti eeya naa.

Ohun-ini 5

iga (h) ti eyikeyi ti idagẹrẹ prism jẹ nigbagbogbo kere ju ipari ti eti ita rẹ. Ati pe giga ti nọmba ti o taara jẹ dogba si eti rẹ.

• Lori ọpọtọ. osi: h = AA₁
• Ninu ọpọtọ. irú: h <AA₁
