M'bukuli, tiwona zinthu zazikulu za polygon wokhazikika ponena za ngodya zake zamkati (kuphatikiza kuchuluka kwake), kuchuluka kwa ma diagonal, pakati pa mabwalo ozungulira komanso olembedwa. Njira zopezera kuchuluka kofunikira (dera ndi kuzungulira kwa chithunzi, ma radii ozungulira) amaganiziridwanso.
Zindikirani: tidawunika tanthauzo la polygon wokhazikika, mawonekedwe ake, zinthu zazikulu ndi mitundu yake.
Nthawi zonse polygon katundu
Katundu 1
Makona amkati mwa polygon wokhazikika (α) ali ofanana wina ndi mzake ndipo akhoza kuwerengedwa ndi chilinganizo:
kumene n ndi chiwerengero cha mbali za chithunzicho.
Katundu 2
Chiwerengero cha ngodya zonse za n-gon ndi: 180° · (n-2).
Katundu 3
chiwerengero cha diagonals (Dn) n-gon yokhazikika imadalira kuchuluka kwa mbali zake (n) ndipo akufotokozedwa motere:
Katundu 4
Mu polygon iliyonse yokhazikika, mutha kulemba bwalo ndikufotokozera mozungulira mozungulira, ndipo malo awo amalumikizana, kuphatikiza ndi pakati pa polygon palokha.
Mwachitsanzo, chithunzi pansipa chikuwonetsa hexagon yokhazikika (hexagon) yokhazikika pamfundo O.
Area (S) opangidwa ndi mabwalo a mphete amawerengedwa mwa kutalika kwa mbali (a) ziwerengero molingana ndi formula:
Pakati pa radii yolembedwa (r) ndi kufotokozedwa (R) zozungulira pali kudalira:
Katundu 5
Kudziwa kutalika kwa mbali (a) polygon wokhazikika, mutha kuwerengera zochulukira izi:
1. Malo (S):
2. Wozungulira (P):
3. Radius wa bwalo lozungulira (R):
4. Radius wa bwalo lolembedwa (r):
Katundu 6
Area (S) polygon wokhazikika amatha kuwonetsedwa motengera utali wa bwalo lozungulira / lolembedwa:
