For a rotation, other than of 180 degrees, it is necessary to specify whether it is clockwise or anticlockwise. Since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.
Yes, it is.
Reflection in the y-axis.

rotation
Rotation.
Dilation, rotation, reflection and translation
No. It would be a diagonal.
A rotation of 180 degrees is equivalent to a double reflection, as both operations flip the object over twice resulting in the same final orientation.
A transformation (this includes reflection, translation, and rotation)
The three transformation in angles are translation , rotation , reflection .
You went 360o in the same direction, so you end up with a circle.
