This is a image displaying symmetry through a tennis court not just in terms of the image itself, having the same lines on each side of the court but also in terms of the sport itself. Often times when watching a match viewers will notice an effect almost like a mirror image on each side of the court, this occurs because tennis players have the same principles in terms of their strokes. This leads to both sides of the court looking extremely similar and displaying tranquility and symmetry in the match.
