  1. UCHBURCHAKLAR 7-sinf Tuzuvchi: №16 SOSHo’qituvchisi Oleinik N.S. Tarjimon: TSHPKQTMOI ratta o’qituvchisi Moxamedjanova A.

  2. Ta’rifi Bir to’g’ri chiziqda yotmagan uchta nuqta va ularni ketma-ket tutashtiruvchi uchta kesmadan iborat geometrik shaklga uchburchak deyiladi. А B C

  3. Uchburchak turlari • O’tkir burchakli uchburchak • O’tmas burchakli uchburchak • To’g’ri burchakli uchburchak

  4. O’tkir burchakli uchburchak • Uchburchakning uchala burchagi o’tkir bo’lsa o’tkir burchakli uchburchak deyiladi.

  5. O’tmas burchakli uchburchak • Uchburchakning bir burchagi o’tmas bo’lsa, o’tmas burchakli uchburchak deyiladi.

  6. To’g’ri burchakli uchburchak B • Uchburchakning bir burchagi to’g’ri bo’lsa to’g’ri burchakli uchburchak deyiladi. • To’g’ri burchak qarshisidagi tomon gipotenuza, qolgan tomonlar katetlari deyiladi. c a 90° C A b

  7. To’g’ri burchakli uchburchak xossalari • 1. To’g’ri burchakli uchburchak o’tkir burchaklari yig’indisi 90°. • 2. To’g’ri burchakli uchburchakning 300 li burchak qarshisidagi kateti gipotenuza yarmiga teng. • 3. To’g’I burchakli uchburchakning kateti gipotenuza yarmiga teng bo’lsa, bu katet qarshisidagi burchak 30° ga teng.

  8. Uchburchaklar Ta’rif: • Ikki tomoni teng bo’lgan uchburchak teng yonli deyiladi. • Hamma tomoni teng bo’lgan uchburchak teng tomonli deyiladi. Xossalari: • 1. Teng yonli uchburchakning asosidagi burchaklari teng. • 2. Teng tomonli uchburchakning bissektrisasi uning ham balandligi, ham medianasi bo’ladi.
