Question 42855: The vertices of ΔABC are A(-3,-4), B(-1,3), C(3,-2). The triangle is rotated 90 degrees counterclockwise.
|0-1|
|1 0| is the rotation matrix used. Find the coordinates of C'.
Thank You

You can put this solution on YOUR website!
The easiest way to see this is to merely graph it.
Since you are rotating it counterclockwise 90 degrees, merely tilt your head
90 degrees CLOCKWISE and then tell me the coordinates of C as it appears to you now...yes, that's it...(2, 3)!
