   Berilgan ko’pburchakka o’xshash ko’pburchakni yasash ketma-ketligini ayting.
   
2. 
   Daftaringizga biror ABCDE beshburchak chizing. Gomotetiya yordamida bu beshburchakka o’xshash, o’xshashlik koeffitsienti 0,5 ga teng bo’lgan beshburchak yasang. Gomotetiya markazi a) C nuqtada; b) beshburchak ichida; d) AB tomonda bo’lgan hollarni alohida ko’ring.
