A rectangle was rotated 270° about the origin. The image is shown. Which points are vertices of the pre-image? Check all that apply. K(–3, –1) M(–3, 2) M(3, 2) N(–3, 1) N(3, 1)

M(3, 2) and N(3, 1)

Step-by-step explanation:

A rectangle was rotated 270° about the origin.

Since it doesn't mention which direction, we will review both clockwise and anti-clockwise rotation.

See attached where top rectangle represents the pre-image before anti-clockwise and bottom one - before clockwise rotation.

Now let's check the points given:

K(–3, –1)

M(–3, 2)

M(3, 2)

N(–3, 1)

N(3, 1)

So based on correct points of pre-image we can state it was rotation anti-clockwise
