(-e, -h)
180 degrees is half a rotation so probably a half.
Not always. It depends where the line of symmetry is located.
depends on the centre of rotation if it's about the origin the x coord is multiplied by -1
yup.
180 degrees
A 180 degree rotation between front and back is normal for US coins.
(-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.
A 180 degree rotation?
(x, y)-----> (-x, -y)
(-4,-3) anything with a 180 degree rotation regardless of being postive or negative is always negative the numbers in parenthesis.
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.
If you mean "Does it have a rotational symmetry", the answer is "Yes." there is a 180 degree rotational symmetry.
Not always. It depends where the line of symmetry is located.
depends on the centre of rotation if it's about the origin the x coord is multiplied by -1
