What happens to the shape when a reflection is performed in geometry?

When a reflection is performed in geometry, the shape flips over a designated line, known as the line of reflection. This process does not alter the size or proportions of the shape, nor does it affect its color or its overall orientation beyond the simple flipping action. The original shape and the reflected shape are congruent; they have the same size and shape but are positioned on opposite sides of the line of reflection. This is an essential property of reflections in Euclidean geometry, illustrating that the orientation of the shape is reversed while maintaining its dimensions and geometric properties.
