In the figure, polygon ABCD is dilated by a factor of 2 to produce A′B′C′D′ with the origin as the center of dilation.

Aqual:

what is the question?

Jade123:

the equation is that it rotates 90 degrees the original points are (-1,-1),(2,-1),(0,1), and (2,2)

Aqual:

ANd the question?

Jade123:

Point A′ is at ,___ and point D′ is at ____.

Jade123:

that's all it gave me and his graph

Aqual:

So it wants to know the location of A and D at each rotation?

Jade123:

yes

Aqual:

And the point of origin?

Aqual:

I mean te point of rotation?

Jade123:

no it doesnt want that just want the coordinates are after you rotate it by 2

Kingtaker435:

point a and d are at (-1,-1) and (2,-1)

Kingtaker435:

does that help

Aqual:

So after the dilation of 2, the coordinates will be multiplied by 2.

Jade123:

ok
