Question

(triangle) NOW is rotated 90 degrees about the origin, draw the image of this rotation

Answer 1

The new coordinates are : N'=(3,-7), O'=(-4,-5), W'=(-1,-1).

If a point $(x,y)$ is rotated $90$ degrees counterclockwise about the origin, it becomes $(-y,x)$.

Here, $N=(-7,-3)$. So, $N'=(3,-7)$

$O=(-5,4)$. So, $O'=(-4,-5)$

$W=(-2,1)$. So, $W'=(-1,-1)$

So, image after rotation is:
