Plane mirrors: re-reflection?

[Mellinia]

Two plane mirrors inclined at an angle [latex]\theta [/latex] to each other, with an object placed between them will create [latex](n-1) \frac {360 ^o}{ \theta } [/latex] of images. Is this because of the repeated reflection of the images?

Are we allowed to produce a mirror lengthwise to show a reflection of an object that would otherwise cannot be located? see attachment.

Yes it is because of repeated reflection on rays.

Talking about the possibility of the pic you uploaded, it depends upon the observer. For Example, get your friend to sit near a dressing table with a large mirror fitted on it. Now you move yourself such that you now take a position as the position of 'object' in this pic. So, you are out of the range of frame of the dressing table but your friend can see you in it, exactly in line to your original position.
