If rectangle ABCD was reflected over the y-axis, reflected over the x-axis,and rotated 180�, where would point A' lie?
OpenStudy (anonymous):
OpenStudy (anonymous):
(1,-1)
(1,1)
(-4,-1)
(-4,1)
OpenStudy (anonymous):
The 1/2 is actually means degrees
OpenStudy (rational):
Take a look at the given diagram,
what are the coordinates of point A ?

try again
OpenStudy (rational):
the x coordinate of A is -4
y coordinate of A is 1
OpenStudy (rational):
so the coordinates of A wud be : (-4, 1)

Okay :)
OpenStudy (rational):
(-4, 1)
reflect over y-axis :
(-4, 1) -> ??
OpenStudy (rational):
where wud it go, after reflecting over y-axis ?
OpenStudy (anonymous):
1,-4?
OpenStudy (anonymous):
No No -1,4

OpenStudy (rational):
nope, reflections will not change the order
OpenStudy (rational):
(-4, 1)
reflect over y-axis :
(-4, 1) -> (4, 1)
OpenStudy (anonymous):
>,< Sorry
OpenStudy (rational):
next reflect this (4, 1) over x-axis
wat wud u get ?
OpenStudy (rational):
reflect over x-axis :
(4, 1) -> ??
