MEDALL AND FAN!!! Which statement is true about figures ABCD and A'B'C'D'? A'B'C'D is obtained by translating ABCD 4 units up and then reflecting it about the y-axis. A'B'C'D is obtained by translating ABCD 4 units right and then reflecting it about the x-axis A'B'C'D is obtained by rotating ABCD counterclockwise by 180 degrees about the origin and then reflecting it about the y-axis. A'B'C'D is obtained by rotating ABCD counterclockwise by 90 degrees about the origin and then reflecting it about the x-axis .

I believe is D because it matches the description|dw:1422293762538:dw|

OpenStudy (mkapad01):

I think it is c

OpenStudy (mkapad01):

this is because there is no way that the triangle was rotated around the origin in 90 degrees

OpenStudy (daniellelovee):

90 degree counterclockwise not clockwise

OpenStudy (daniellelovee):

but if something is between those 2

OpenStudy (mkapad01):

|dw:1422294762560:dw| it is 180 because when you see how b turns clockwise, it is definitely not 90
