Me ajude pfv

Answer 1

A) DAB^2= (x4 - x2)^2 + (y4 - y2)^2
DAB^2= ( 4 - 2 )^2 + ( -1 - 1)^2
DAB^2= ( 2)^2 + ( -2)^2
DAB= 4 + 4
DAB= RAIZ DE 8

B) DCD^2 = (x-3 - x4)^2 + (y -3 - y4)^2
DCD^2= ( -3 - 4)^2 + ( 2 - 6)^2
DCD^2= (-7)^2 + (-4)^2
DCD= 49 + 16
DCD= Raiz de 65.

C) DEF^2= (x-1 - x2)^2 + (y-1 - y2)^2
DEF^2= ( -1 - 2)^2 + (3 - 5)^2
DEF^2= ( -3)^2 + ( -2)^2
DEF= 9 + 4
DEF= Raiz de 13.

D) DGH^2= ( x-8 - x4)^2 + ( y-8 - y4)^2
DGH^2= ( -8 - 4)^2 + ( 3 - 8)^2
DGH^2= ( -12)^2 + ( -5)^2
DGH= 144 + 25
DGH= Raiz de 169
DGH= 13.
