Prosze o rozwiazanie ćwiczeń :D dam naj :)  Są to zadania z geometrii analitycznej  z góry dziekiiiiiii :D

1 |AC|=[latex] sqrt{(4-1) ^{2} + (-1-2)^2}= sqrt{18}= 3sqrt{2} [/latex]   |AB|=√25=5   |BC|=[latex] sqrt{(5-4)^2+(5+1)^2} = sqrt{37} [/latex] 2 |AB|= [latex] sqrt{(-5-3)^2+(-5-1)^2}= sqrt{100}= 10 [/latex]    |BC|= [latex] sqrt{(3+1)^2+(1-4)^2}= sqrt{25} = 5 [/latex]    |CD|=[latex] sqrt{(-1)^2+(4-2)^2}= sqrt{5} [/latex]    |AD|=[latex] sqrt{(-5)^2+(-5-2)^2} = sqrt{74} [/latex] 3a) [latex]( frac{-7-1}{2}, frac{4-6}{2}) = (-4,-1)[/latex] b)[latex] ( frac{-9+3}{2}, frac{ frac{1}{2} + frac{1}{4} }{2})=(-3, frac{3}{8}) [/latex]
