What is reflection across x-axis
The reflection of a point, line, or shape across the x-axis is a transformation that results in a mirror image with respect to the x-axis.
This means that each point (x, y) in the original figure is transformed to the point (x, -y) in its reflected image.
Rotating a point or object by 180 degrees about the origin is a transformation where each point is moved along a circular path centered at the origin, and the angle of rotation is 180 degrees.
This means that each point (x, y) is transformed to the point (-x, -y).
