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

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 $(-5,-4)$

A triangle's coordinates are (-2, 1), (-6, 1),(-2, 1), (-6, 1), and (-4,5)(-4,5). After the triangle is rotated clockwise 270° about the origin, what are the new coordinates?
