Asked by Randi

When an object can be shifted, say to the left or right, and still remains the same; this is an example of what time of symmetry
Answered by Randi
Is it bilateral symmetry
Answered by bobpursley
bilateral symmetry is a mirror image along a line, so each side is NOT the same, but reversed.

shifting left to right remaining the same is translational symmetry http://en.wikipedia.org/wiki/Translational_symmetry
