Pyramide - Azwi kandi nka Pyramide
Ibisobanuro ku bicuruzwa
Urufatiro rwa piramide:Polygon muri piramide yitwa ishingiro rya piramide.
Impande za piramide:Amaso ya piramide itari shingiro yitwa impande za piramide. .
Impande z'uruhande rwa piramide:Impande zisanzwe zimpande zitwa kuruhande rwuruhande rwa piramide.
Isonga rya piramide:Apex isanzwe yimpande muri piramide yitwa apex ya piramide.
Uburebure bwa piramide:Intera kuva hejuru ya piramide kugera kuri base yitwa uburebure bwa piramide.
Isura ya diagonal ya piramide:Igice cya piramide inyura mu mpande ebyiri zidahuje impande zitwa isura ya diagonal.
Ibiranga
Pyramide nubwoko bwingenzi bwa polyhedron, ifite ibintu bibiri byingenzi biranga:
Isura imwe ni polygon;
HeAhasigaye mu maso ni mpandeshatu zifite vertex imwe, kandi byombi ni ngombwa.
Kubwibyo, isura imwe ya piramide ni polygonal, indi sura ni mpandeshatu. Ariko nanone menya ko "isura imwe ni polygon, naho mumaso isigaye ni mpandeshatu" geometrie ntabwo byanze bikunze piramide.
Theorem
Theorem: Niba piramide yaciwe nindege ibangikanye na base, igice cyavuyemo gisa nikibanza, kandi igipimo cyubuso bwigice nigice cyibanze kiringaniye na kwadrati ya kare ya intera kuva kuri apex kugeza ku gice kugeza ku burebure bwa piramide.
Kugabanuka 1: Niba piramide yaciwe nindege ibangikanye na base, noneho impande zuruhande nuburebure bwa piramide bigabanijwemo igipimo kimwe nigice cyumurongo.
Kugabanuka 2: Niba piramide yaciwe nindege ibangikanye na base, ikigereranyo cyubuso bwuruhande rwa piramide ntoya na piramide yumwimerere nacyo gihwanye na kwadrato ya kare yuburebure bujyanye, cyangwa igipimo cyibice byabo fatizo.
