A reflection can be thought of as folding or "flipping" an object over the line of reflection.
• The original object is called the pre-image, and the reflection is called the image.
• The image is usually labeled using a prime symbol, such as A'B'C'.
• An object and its reflection have the same shape and size, but the figures face in opposite directions. The objects appear as if they are mirror reflections, with right and left reversed.
