Дано трикутники ABC і A1B1C1. Доведіть, що справедлива рівність (AA_1 ) ⃗ + (BB_1 ) ⃗ + (CC_1 ) ⃗ = (AB_1 ) ⃗ + (BC_1 ) ⃗ + (CA_1 ) ⃗ Довести: (AA_1 ) ⃗ + (BB_1 ) ⃗ + (CC_1 ) ⃗ = (AB_1 ) ⃗ + (BC_1 ) ⃗ + (CA_1 ) ⃗ (AA_1 ) ⃗ + (BB_1 ) ⃗ + (CC_1 ) ⃗ – (AB_1 ) ⃗ – (BC_1 ) ⃗ – (CA_1 ) ⃗ = 0 ⃗. (B_1 A_1 ) ⃗ + (C_1 B_1 ) ⃗ + (A_1 C_1 ) ⃗ = 0 ⃗. (C_1 C_1 ) ⃗ = 0 ⃗ правильно.
