Main Question or Discussion Point

So,does a plane mirror(or a group of plane mirrors) ever form an inverted i.e. upside down image ?
According to my own understanding, no.
But in our home work this question was asked.
So, is it possible??

'Lateral' inversion is called that because of the geometry of the images in a mirror. If you lay a mirror on the ground and look at the reflection of a tree, in the distance, what will it look like? Draw a circle with an arrow pointing tangentially in a clockwise direction around the circle, how does it look in the mirror, whether it's next to your face or on the other side of the room, looking obliquely through the mirror? Clockwise or anticlockwise?

And what did I answer? You need to do some thinking. Did you try the mirror on the floor test?
