Best ResponseYou've already chosen the best response.0A reflection over the xaxis changes the sign on the ycoordinate. A reflection over the yaxis changes the sign on the xcoordinate. Rotating by 180 degrees reverses the x and ycoordinates.

Best ResponseYou've already chosen the best response.0Looking at the given diagram, what are the coordinates of point B?

Best ResponseYou've already chosen the best response.0Great. So first apply a reflection over the xaxis. As I said earlier, the sign on the ycoordinate changes. What are the new coordinates?

Best ResponseYou've already chosen the best response.0Change the sign on the ycoordinate. It it's positive, it becomes negative. If it's negative, it becomes positive.

Best ResponseYou've already chosen the best response.0Good. Now apply the reflection over the yaxis. In this transformation, the sign on the xcoordinate changes. What does that give you?

Best ResponseYou've already chosen the best response.0Good. Now finally, rotate by 180 degrees. In this transformation, both coordinate change sign (I messed up when I tried to explain above). What does this give you?

Best ResponseYou've already chosen the best response.0Yup. Draw it out for yourself to confirm.

Best ResponseYou've already chosen the best response.0That's right. It ends up right back where it started.

Best ResponseYou've already chosen the best response.0You have performed three transformations, reflection across xaxis, reflection across yaxis, and rotation of 180 degrees. Not just a 180degree rotation.

Best ResponseYou've already chosen the best response.0Well then, draw it out. That's what you should be doing anyway. dw:1442273486042:dw
