Equivalently , a surface is orientable if a two-dimensional figure such as in the space can not be moved around the space and back to where it started so that it looks like its own mirror image .

In the MISC@1 space NUMBER@1 is called orientable if a two-dimensional figure -LRB- for example , -RRB- can not be moved around the surface and back to where it started so that it looks like its own mirror image -LRB- -RRB- .
