= ( -2 , - 3 , - 4) - (1 , 2 , 3)
= ( -3 , -5 , -7)
IACI = √(-3² + -5² + -7²)
= √ 9 + 25 + 49
= √83
vektor NT = t - n
= (-2 , 0 , 5) - (1 , - 2 , 4)
= (-3 , 2 , 1)
INTI = √ {(-3)² + 2² + 1²}
= √ 9 + 4 + 1
= √ 14
vektor IK = k - i
= (0 , -1 , -2) - (2 , 3 , -5)
= (-2 , -4 , 3)
IIKI = √{(-2)² + (-4)² + 3²
= √4 + 16 + 9
= √29
vektor DE = e - d
= (2 , 4 . 3) - (0 , -2 , 3)
= (2 , 5 , 0)
IDEI = √ 2² + 5² + 0²
= √ 4 + 25
= √ 29
