Question 797359
Quadrilateral TUVW with T (-4,2) U (-2,4) V (0,2) and W(-2,-4)rotated 90 degrees counterclockwise about the origin. 
       What I don't really understand is what the Quadrilateral looks like on the graph, after the rotation, and what the coordinates are for the new rotated shape. 
--------------------
It will be the same shape, just rotated.
T (-4,2) --> T' (-2,-4)
U (-2,4) --> U' (-4,-2)
V (0,2) --> V' (-2,0)
W (-2,-4) --> W' (4,-2)
=======================
The distance from the Origin remains the same after rotation.
The x & y are swapped (for 90 deg rotation).  The signs are determined by the ending quadrant.

email via the TY note and I'll send a graph.
