Muchinyorwa chino, tichatarisa tsananguro uye zvakakosha zvimiro zveisosceles trapezoid.
Yeuka kuti trapezoid inonzi maringe (kana isosceles) kana mativi ayo akaenzana, kureva AB = CD.
Chivakwa 1
Makona pane chero mabhesi eisosceles trapezoid akaenzana.
- ∠DAB = ∠ADC = a
- ∠ABC = ∠DCB = b
Chivakwa 2
Huwandu hwemakona akapesana e trapezoid ndeye 180 °.
Pamufananidzo uri pamusoro: α + β = 180°.
Chivakwa 3
Iyo diagonals ye isosceles trapezoid ine hurefu hwakafanana.
AC = BD = d
Chivakwa 4
Urefu hwe isosceles trapezoid BEyakadzikiswa pahwaro hwehurefu hukuru AD, inoiparadzanisa muzvikamu zviviri: yekutanga yakaenzana nehafu yehuwandu hwezvigadziko, yechipiri hafu yekusiyana kwavo.
Chivakwa 5
Mutsara chikamu MNkubatanidza mapoinzi ezvigadziko zveisosceles trapezoid iri perpendicular kune aya mabhesi.
Mutsetse unopfuura nepakati pezvigadziko zve isosceles trapezoid unonzi wayo akabatana symmetry.
Chivakwa 6
Denderedzwa rinogona kutenderedzwa kutenderedza chero isosceles trapezoid.
Chivakwa 7
Kana huwandu hwezvigadziko zve isosceles trapezoid yakaenzana nekaviri kureba kwerutivi rwayo, ipapo denderedzwa rinogona kunyorwa mairi.
Iyo radius yedenderedzwa rakadaro yakaenzana nehafu yehurefu hwetrapezoid, kureva R = h/2.
Cherechedza: zvimwe zvezvinhu zvinoshanda kune ese marudzi e trapezoid anopiwa mukudhindwa kwedu -.
