1.
A= (-4,2) , B = ( -8 ,2 )
za = - 4 , xb = - 8 , ya = 2 , yb = 2
IABI = √[(xb - xa)² + (yb - ya)²] = √[(- 8 + 4)² + ( 2 - 2)²]= √[(- 4)² + 0²] =
= √16 = 4 , więc Fałsz
zad 2
C = ( 1 , - 2 ) , D = ( 1 , 5 )
xc = 1 , xd = 1 , yc = - 2 , yd = 5
ICDI = √[(xd - xc)² + (yd - yc)²] = √[(1 - 1)² + ( 5+ 2)²] = √(0² + 7²) =
= √7² = 7 , więc Fałsz
