Graph the polygon with vertices A(−3,−1), B(2, 2), C(3,−3)and its image after a rotation 90 degrees about the origin.

Question

What are the coordinates for polygon ABC after its rotation of 90 degrees about the origin?

Please show all the work on how you got your answer.

Answer 1

There is a song : )
It goes...
"90 degrees is just a breeze when you map negative y comma x"
that is
(x,y) becomes (-y,x)
So point A(-3,-1) has an x value of -3 and a y value of -1
So in the (-y, x)
the y value of -1 goes to the first place in the brackets, but we need -y so that is
- - 1 or 1
(1, x)
and recall our x value was -3 so (-y,x) becomes (1, -3)
Now you do the rest : )
