ganeshie8 (ganeshie8):

1/2 turn means rotating 180 degrees

ganeshie8 (ganeshie8):

So, A goes to the other side of P

ganeshie8 (ganeshie8):

count the # of grids between P and A

ganeshie8 (ganeshie8):

take it twice to get the distance between A and A'

OpenStudy (anonymous):

ok i get it but on the other hand i dont, any ways to explaine it differently

ganeshie8 (ganeshie8):

here is ur second chance : 1) look at the given graph, whats the distance between P and A ?

ganeshie8 (ganeshie8):

to find the distance between P and A, simply count the number of grids.

OpenStudy (anonymous):

6

ganeshie8 (ganeshie8):

Yes !! 6 is right

OpenStudy (anonymous):

so the answer is B

ganeshie8 (ganeshie8):

Nope, the question is not about distance between P and A

OpenStudy (anonymous):

ok

ganeshie8 (ganeshie8):

we need to rotate this point half turn.

Miracrown (miracrown):

and when you rotate it, you're rotating 1/2 turn around P, to get this, yes . . .
