I dont understand How they got that answer

anonymous · Answer

It says The distance between P1 and P2 denoted by |P1P2| or d,=
but then at the bottom it says (distance between P1 and P3)^2+(Distance between P3 and P2)^2

It is a little odd.  Answer these...

What is $|P_{1}P_{3}|$?

What is $|P_{2}P_{3}|$?

anonymous · Answer

P(1)( -4,-2) P(3) (3,-2)     P(2) (3,4)

That is not the question.  I see the coordinates of the points.  The question is, after introducing the notation $|pq|$, to mean the distance between two points, p and q, what are the two distances I requested?
