Muchinyorwa chino, tichaona nzira yekuverenga iyo perimeter ye katatu uye kuongorora mienzaniso yekugadzirisa matambudziko.
Perimeter Fomula
Perimeter (P) yegonyo ripi zvaro yakaenzana nehuwandu hwehurefu hwemativi ayo ose.
P = a + b + c
Perimeter ye isosceles triangle
Isosceles triangle igonyonhatu rine mativi maviri akaenzana (ngatitorei se b) Side a, ine hurefu hwakasiyana kubva kumativi, ndiyo nheyo. Nokudaro, perimeter inogona kuverengwa sezvinotevera:
P = a + 2b
Perimeter ye equilateral triangle
Gonyonhatu yakaenzana kana yekurudyi inonzi, umo mativi ese akaenzana (ngatitorei se a) Iyo perimeter yemufananidzo wakadaro inoverengerwa seizvi:
P = 3a
Mienzaniso yemabasa
Basa 1
Tsvaga perimeter yekona kana mativi ayo akaenzana: 3, 4 uye 5 cm.
Sarudzo:
Isu tinotsiva huwandu hunozivikanwa nemamiriro edambudziko mune fomula uye tinotora:
P=3cm+4cm+5cm=12cm.
Basa 2
Tsvaga perimeter ye isosceles triangle kana chigadziko chayo chiri 10 cm uye rutivi rwayo 8 cm.
Sarudzo:
Sezvatinoziva, mativi e isosceles triangle akaenzana, saka:
P = 10 masendimita + 2 ⋅ 8 masendimita = 26 cm.
