Darsning texnologik xaritasi

Natija: Muntazam beshburchakning barcha diagonallari teng.

IV. mustahkamlash: darslikdagi masalalarni yechish.

№3 a) n=3; b) n=5; d) n=6; e)n=10; f)n=18; bo’lsa, muntazam n burchakning

burchaklarini toping.

Yechish:

a)n=3 bolgan hol uchun burchak kattaligi α ni topamiz: α= =

b) n=5; α= = ; d) n=6; α= =

e) n=10; α= = ; f)n=18; α= =

№4 muntazam n burchakning tashqi burchagi nimaga teng: a) n=3; b) n=5; d) n=6; e)n=10; f)n=12

Yechish:

a)n=3 bolgan hol uchun burchak kattaligi α ni topamiz:

α= 180⁰- = 180⁰-

b) n=5; α= 180⁰ - = 180⁰ -

d) n=6; α=180⁰ - = 180⁰ -

e) n=10 α=180⁰ - = 180⁰ -

f)n=12; α=180⁰ - = 180⁰ -

mustaqil ish: 6-masalani yechish

Yechish:

a) α=60⁰ ; b)90⁰ d) 150⁰ bo’lsa ,ko’pburchak tomonlari sonini toping

V.darsni yakunlash va xulosalash: Muntazam ko’pburchaklarga ta’rif, teorema, natijani takrorlash, o’quvchilarning mavzuga oid tushunmagan savollari bo’lsa javob berish, o’quvchilar to’plagan ballar e’lon qilinib, kundaliklarga va jurnallarga qo’yiladi.

VI. Uyga vazifa: 9-sinf geometriya darsligi 95- bet 1,2,4-masalalarni yechish.
