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).
(x, y)-----> (-x, -y)
Because 180 degrees clockwise is the same as 180 degrees counterclockwise.
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.
180 degrees
360 degrees would be one full rotation. 180 degrees would be a half rotation. 360+180=540 So it would be a rotation and a half.
(x, y)-----> (-x, -y)
Because 180 degrees clockwise is the same as 180 degrees counterclockwise.
Fomula(work with both clockwise/counterclockwise):(-x,-y)
The rule for a rotation by 180° about the origin is (x,y)→(−x,−y) .
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.
(x, y) -> (-x, -y)
180 degrees
A 180 degree rotation between front and back is normal for US coins.
It is (-1, 6).Also, if the rotation is 180 degrees, then clockwise or anticlockwise are irrelevant.It is (-1, 6).
(-e, -h)
180 degrees is half a rotation so probably a half.
360 degrees would be one full rotation. 180 degrees would be a half rotation. 360+180=540 So it would be a rotation and a half.
