Fomula(work with both clockwise/counterclockwise):(-x,-y)

180 degrees is half a rotation so probably a half.
The formula is (N-2)180 degrees.
depends on the centre of rotation if it's about the origin the x coord is multiplied by -1
change the sign, but DONT switch the coordinates (:
A 180° rotation is half a rotation and it doesn't matter if it is clockwise of counter clockwise. When rotating 180° about the origin, the x-coordinate and y-coordinates change sign Thus (1, -6) → (-1, 6) after rotating 180° around the origin.
Because 180 degrees clockwise is the same as 180 degrees counterclockwise.
180 degrees in the plane perpendicular to the xy plane. In general, no rotation in the (x, y) plane will take it to (-x, y) unless x = y (or -y) and, in that case it is a 270 degree clockwise rotation.
(x, y)-----> (-x, -y)
It is (-1, 6).Also, if the rotation is 180 degrees, then clockwise or anticlockwise are irrelevant.It is (-1, 6).
Fomula(work with both clockwise/counterclockwise):(-x,-y)
180 degrees
A 180 degree rotation between front and back is normal for US coins.
First of all, if the rotation is 180 degrees then there is no difference clockwise and anti-clockwise so the inclusion of clockwise in the question is redundant. In terms of the coordinate plane, the signs of all coordinates are switched: from + to - and from - to +. So (2, 3) becomes (-2, -3), (-2, 3) becomes (2, -3), (2, -3) becomes (-2, 3) and (-2, -3) becomes (2, 3).
(-e, -h)
our point A(x,y) becomes A'(-x,-y).
