Reflection:

When any object is placed in front of a mirror, its image is formed at the same distance behind the mirror as the object is front of it.

Invariant Point:

Any point that remains unaltered under a given transformation is called invariant. For example:

1. Reflection of  in  would remain same as 
2. Reflection of  in  would remain same as 
3. Reflection of  in  would remain same as 

Remember, in case of an Invariant point, the point itself is its own image. Similarly, every point  in a like  is reflected in  itself , the point is invariant.

Reflection Definition:

In Geometry, a reflection is known as a flip. A reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection. A figure is said to be a reflection of the other figure, then every point in a figure is at equidistant from each corresponding point in another figure. The reflected image should have the same shape and size, but the image faces in the opposite direction. In reflection, translation may also take place because of its changes in the position. Here, the original image is called pre-image, and its reflection is called image. The representation of pre-image and image are ABC and A’B’C’ respectively. The reflection transformation may be in reference to the coordinate system (X and Y-axis).

Reflection over X-axis:

When a point is reflected across the X-axis, the x-coordinates remain the same. But the Y-coordinates are transformed into its opposite signs.

Reflection over Y-axis:

When a point is reflected across the Y-axis, the Y-coordinates remain the same. But the X-coordinates is transformed into its opposite signs.

Reflection over Y = X:

When a point is reflected across the line y = x, the x-coordinates and y-coordinates change their place. Similarly, when a point is reflected across the line y = -x, the x-coordinates and y-coordinates change their place and are negated.
