In geometry, a reflection is a transformation that produces a mirror image of a figure across a line (in two dimensions) or a plane (in three dimensions). Reflection changes the orientation of the figure but does not change its size.
When you reflect a geometric shape, every point on the shape is mapped to a corresponding point on the opposite side of the line or plane, maintaining the same distance from the line or plane but reversing the direction.
For example, if you reflect a triangle over a line, the triangle will remain congruent to the original; the size and shape will not change, but its orientation will be flipped. Therefore, reflection changes the orientation of the figure while preserving its size.
