Plane figures and solids can be changed (or transformed) by translation, reflection and dilation. The symmetry of shapes is related to translation, reflection and rotation. Triangle ABC and its reflection A'B'C' have the same size and shape, that is they are congruent. A translation is defined by specifying the distance and the direction of a movement. For example, triangle ABC is translated by 2 units to the right. Triangle ABC and its image A'B'C' have the same size and shape.
A Reflection is a transformation in which the figure is the mirror image of the other. 1  Reflection can also be called as flip. 2  In above figure, one figure is the mirror image of the other. So, the transformation is a reflection.  A reflection is the mirror image.
