Verena because AB is perpendicular on BC

Step-by-step explanation:

first need to find the length of each side :

AB=Distance between two points =

√(xB-xA)^2+((yB-yA)^2=√(4-2)^2+(4-0)^2=√20=2√5

BC do the same =d = √(xb - xc)^2 + (yb - yc)^2 =√5

CB the same (base) : d = √(xc - xb)^2 + (yc - yb)^2 =√5

AC=d = √(xa - xc)^2 + (ya - yc)^2 =√25=5

find the slope of the line to see if the two lines are perpendicular the slope has to be negative reciprocal

for BC the slope is m=y2-y1/x2-x1=-1/2

for AC the slope is 3/4

for AB and BC the slope

AB slope  m=2

BC slope -1/2

AB is perpendicular on BC
