Which sequence of transformations will change figure PQRS to figure P′Q′R′S′?
Figure :
http://prntscr.com/7t9ncj
Counterclockwise rotation about the origin by 180 degrees followed by reflection about the xaxis
Counterclockwise rotation about the origin by 180 degrees followed by reflection about the yaxis
Counterclockwise rotation about the origin by 270 degrees followed by reflection about the xaxis
Counterclockwise rotation about the origin by 270 degrees followed by reflection about the yaxis

Best ResponseYou've already chosen the best response.0We can also use common sense. Because a reflection across the x axis is highly unlikely unless it goes 360, which none of the above have, we can eliminate the x axis choices.

Best ResponseYou've already chosen the best response.0Then 270 degree turn would but it in quadrant 1, so there goes D. All we have left is A. and that is the answer
