Reflection over a point is equivalent to enlargement with the same point as the focus of enlargement and a scale factor of -1.
In an isometry, the point of transformation that does not move is called the "fixed point." This point remains unchanged during the transformation, whether it is a translation, rotation, or reflection. For example, in a rotation, the center of rotation serves as the fixed point, while in a reflection, the line of reflection equidistantly bisects the space, with points on the line remaining unchanged.
Geometry reflection: a flip of a figure over a specific point or line Real life situation: mirror or reflecting pool.
A glide reflection is a combination of a reflection in a line and a translation along that line. This can be done in either order. A rotational transformation is a rotation around a fixed point or axis.
A rotation turns a shape through an angle about a fixed point
A point is a vertex
In an isometry, the point of transformation that does not move is called the "fixed point." This point remains unchanged during the transformation, whether it is a translation, rotation, or reflection. For example, in a rotation, the center of rotation serves as the fixed point, while in a reflection, the line of reflection equidistantly bisects the space, with points on the line remaining unchanged.
The transformation is called a reflection. In a reflection, each point of the figure is mapped to a corresponding point on the opposite side of the mirror line, maintaining the same distance from the line. This creates a mirror image of the original figure.

A glide reflection is a combination of a reflection in a line and a translation along that line. This can be done in either order. A rotational transformation is a rotation around a fixed point or axis.
A rotation turns a shape through an angle about a fixed point
In the context of transformations, a point that does not move is often referred to as a fixed point. This means that when a transformation, such as rotation, reflection, or translation, is applied, the fixed point remains unchanged in its position. Fixed points are important in understanding the behavior of various transformations and can serve as reference points for analyzing the effects of the transformation on other points in the space.
Rotation is a transformation that spins an object on a specific point. In Adobe Illustrator, an object's default rotation point is its centre.Reflection is a transformation that flips an object over and across a specific axis. In Adobe Illustrator, an object's default reflection axis runs vertically through its centre.
A rotation is a transformation that turns an object around a fixed point. It changes the orientation of the object without changing its shape or size. Rotations are a type of transformation that can be applied to objects in geometry to change their position or direction.
A type of transformation where an original figure is flipped over a line onto its image is called reflection. In this process, each point of the original figure is mapped to a corresponding point on the opposite side of the line, maintaining equal distance from the line of reflection. This creates a mirror image of the original figure.
To reflect a point across the origin, you simply change the sign of both the x- and y-coordinates of the point. This transformation involves multiplying the coordinates by -1.
A transformation in which you flip a figure across a mirror line is called a reflection. During this process, each point of the figure is mapped to a corresponding point on the opposite side of the mirror line, maintaining the same distance from the line. This creates a mirror image of the original figure. Reflection is one of the basic geometric transformations, along with translation and rotation.
