New coordinates are #(-1,-2)#, #(-1,-6)# and #(-5,-4)#

Explanation:

A clockwise rotation of #270^@# changes coordinates of a point #(x,y)# to #(-y,x)#

Hence a triangle's coordinates, which are #(-2,1)#, #(-6,1)# and #(-4,5)# after clockwise rotation of #270^@# changes to

#(-1,-2)#, #(-1,-6)# and #(-5,-4)#
