New coordinates of the triangle after dilation are

$color(blue)(A’ (-1,-1), B’ (-1,-2), C’ (-5/2, -1)$

Coordinates of the triangle $A (2,2), B (2,4), C (5,2)$ dilated around origin by factor (-1/2).

$A’ ((x),(y)) = (-1/2) * ((2),(2)) = ((-1),(-1))$

$B’ ((x),(y)) = (-1/2) * ((2),(4)) = ((-1),(-2))$

$C’ ((x),(y)) = (-1/2) * ((5),(2)) = ((-5/2),(-1))$

If the coordinates of a triangle are (2,2), (2,4)(2,2),(2,4)(2,2), (2,4), and (5,2)(5,2)(5,2), what are the new coordinates after a dilation of -1/2?
