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.
Reflections are all around us. You see your reflection in the mirror every morning. If you're out on a calm lake, you may see the reflections of trees and mountains in the water. A reflection in math is the flipping of a point or figure over a line of reflection (the mirror line). The key word here is flipped. A reflection flips an image.
