Mukati
Muchinyorwa chino, tichatarisa zvinhu zvikuru zvepiramidhi (zvichienderana nemicheto yemativi, zviso, zvakanyorwa uye zvinotsanangurwa mujinga redenderedzwa), zvichivaperekedza nemifananidzo yekuona kuti ione zviri nani ruzivo rwakaratidzwa.
Cherechedza: isu takaongorora tsananguro yepiramidhi, zvinhu zvayo zvikuru uye marudzi mukati, saka hatizogara pazviri zvakadzama pano.
piramidhi zvinhu
Piramidhi ine mbabvu dzakaenzana
Chivakwa 1
Makona ese ari pakati pemakona emativi uye hwaro hwepiramidhi akaenzana.
∠EAC = ∠ECA = ∠EBD = ∠EDB = a
Chivakwa 2
Denderedzwa rinogona kutsanangurwa rakatenderedza chigadziko chepiramidhi, pakati pacho chinopindirana nekuratidzwa kwepamusoro pachigadziko chayo.
- nguva F - vertex fungidziro E pahwaro ABCD; iriwo pakati penheyo iyi.
- R ndiyo radius yedenderedzwa rakatenderedzwa.
Zviso zveparutivi zvepiramidhi zvakarerekera kunheyo pakona imwechete.
Chivakwa 3
Denderedzwa rinogona kunyorwa pazasi pepiramidhi, pakati payo inopindirana nekuratidzwa kweiyo vertex pachigadziko chemufananidzo.
Chivakwa 4
Zvose zvikwiriso zvemativi zviso zvepiramidi zvakaenzana kune mumwe nemumwe.
EL = EM = EN = EK
Cherechedza: kune zvivakwa zvakanyorwa pamusoro, maumbirwo akadzokera kumashure ichokwadi zvakare. Somuenzaniso, nokuda Zvivakwa 1: kana makona ose pakati pemakona emativi uye ndege yechigadziko chepiramidi yakaenzana, ipapo mipendero iyi ine urefu hwakafanana.
