A(-2,1) ->(-1,-2) ->(-1.5,-3)
B(0,1)-> (-1,0)-> (-1.5,0)
C(-2,-3)->(3,-2) ->(4.5,-3)
What this trying to show is the first bracket is the points of a,b,c and if rotated clockwise you will get the “second bracket”. Then I used the center of dilation which is 3/2 but transformed it into a decimal 1.5 then multiplied by each numbers in the “second bracket” to get the “third bracket”. The bracket are the parentheses. I HOPE THIS HELPS
