Incident Angle = Resultant Angle!

There is a ball in a square. I threw the ball at an incident angle of 45 degrees at the square's side.
If the ball will indefinitely continue to move inside of the square, bouncing everytime it touches a surface, will it ever reach the center of the square?
Maybe
No
Yes

The ball will continue to move along the sides of a rectangle the diagonals of which meet at the centre of the square.
