They change the orientation.
In its normal orientation the parallel sides of a trapezium are horizontal. In that case it will have no perpendicular lines. But turn the figure through 90 degrees and it has two!In its normal orientation the parallel sides of a trapezium are horizontal. In that case it will have no perpendicular lines.

Because a reflection reverses the direction of the component of the wave vector of the light hitting the reflecting surface which is orthogonal to the surface. The component parallel to the surface will not change. This means the light going towards a mirror, will go away from the mirror after reflection. But if it went from the left to the right, it will continue to go from the left to the right. Same with up and down. In three dimensions this is the same as changing the handedness of the image.
A rotation is a transformations when a figure is turned around a point called the point of rotation. The image has the same lengths and angle measures, and differs only in position. Rotations that are counterclockwise are rotations of positive angles. All rotations are assumed to be about the origin. R90 deg (x, y) = (-y, x) R180 deg (x, y) = (-x, -y) R270 deg (x, y) = (y, -x) R360 deg (x, y) = (x, y)

Rotation, in the plane of the grid, through 180 degrees.
Reflections, translations, rotations.
It's a transformation that's order of the letters like ABCD of a figure don't change when transformed.

orientation
This is called the Orientation.
Reflections, translations, and rotations are considered rigid motions because they preserve the size and shape of the original figure. These transformations do not distort the object in any way, maintaining the distances between points and angles within the figure. As a result, the object's properties such as perimeter, area, and angles remain unchanged after undergoing these transformations.
It is moved across the plane. Its size or orientation are not changed.
It is moving a figure horizontally and/or vertically but keeping it of the same size and orientation.
The same figure. A translation simply moves the figure somewhere else, without changing its shape or size.
