Answer :
Solution
for this case we can solve the question with the following operations:
[tex]AB=\sqrt[]{(0-8)^2+(-7-7)^2}=\sqrt[]{260}[/tex]And similar:
[tex]AC=\sqrt[]{(-8-8)^2+(-5+7)^2}=\sqrt[]{260}[/tex]Then since AB = AC we can conclude that A is equidistant from the endpoints of the segment BC
