Pyramid-Kuma An sanshi da Dala
Bayanin Samfura
Tushen dala:A polygon a cikin dala ana kiransa tushe na dala.
Gefen dala:Fuskokin dala ban da tushe ana kiran bangarorin dala. .
Gefen dala:Gefen gama gari na ɓangarorin maƙwabta ana kiransa gefen gefen dala.
Koli na dala:Babban koli na gama gari a cikin dala ana kiransa koli na dala.
Tsayin dala:Nisa daga kololuwar dala zuwa gindi ana kiran tsayin dala.
Fuskar diagonal na dala:Bangaren dala da ke wucewa ta gefuna biyu da ba maƙwabta ba ana kiran fuskar diagonal.
Halaye
Pyramid wani nau'i ne mai mahimmanci na polyhedron, yana da mahimman halaye guda biyu:
① Fuska guda ɗaya ce;
②Sauran fuskokin triangles ne masu kima na gama-gari, kuma biyun ba su da makawa.
Don haka, fuskar dala ɗaya ɗaya ce, ɗayan fuskokin kuma masu siffar uku. Amma kuma a lura da cewa “fuskar guda ɗaya ce mai polygon, sauran fuskokin kuma masu triangles ne” geometry ba lallai ba ne dala.
Theorem
Theorem: Idan jirgin sama ya yanke dala daidai da tushe, sashin da aka samu yayi kama da tushe, kuma rabon yanki na yanki da yanki na tushe yana daidai da ma'auni na murabba'in nisa daga tushe. koli zuwa sashin zuwa tsayin dala.
Rage 1: Idan jirgin sama ya yanke dala daidai da tushe, to an raba gefen gefe da tsayin dala zuwa ma'auni iri ɗaya ta sashin layi.
Rage 2: Idan jirgin sama ya yanke dala daidai da tushe, rabon gefen gefen ƙaramin dala zuwa ainihin dala shima daidai yake da murabba'in murabba'in tsayin tsayin su, ko ma'aunin yanki na tushe.
