maths question (1 Viewer)

i have a quick maths question which i need help with,

below:

The diagram shows a green star (mind my paint drawing) with its centre at co-ordinates (-2,2). The star was rotated 180 degrees about a point, P, until its centre was at (6,-4). What were the co-ordinates of the point, P, about which the star was rotated?





thanks in advance, lookoutastroboy

I think you just find the midpoint cause 180 is a straight line. So P(2,-1). But I really have no idea.
