(-e, -h)
depends on the centre of rotation if it's about the origin the x coord is multiplied by -1
Not always. It depends where the line of symmetry is located.
180 degrees is half a rotation so probably a half.
yup.
No, a triangle does not have point symmetry. Point symmetry occurs when an object or shape remains the same after being rotated 180 degrees around a central point. In the case of a triangle, it does not have point symmetry because it does not look the same after a 180-degree rotation.

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
A 180 degree rotation between front and back is normal for US coins.
A 180 Degree shape would be a line a straight line or diagnal like this: _____________
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?
A rotation turns a shape through an angle at a fixed point as for example if you turn around backwards that will be a rotation of 180 degrees.
(-4,-3) anything with a 180 degree rotation regardless of being postive or negative is always negative the numbers in parenthesis.
If you mean "Does it have a rotational symmetry", the answer is "Yes." there is a 180 degree rotational symmetry.
