Do Convex Lenses Flip Images Horizontally and Veritcally?

Question

I know that images are flipped upside down (vertically) when looking through a lens, but are they also flipped horizontally in a convex lens?

Answer 1

Yes, if it is upside down, it is also flipped horizontally. Only the virtual image when the object is at a distance less than the focal length F), is without any inversion, vertical or lateral.
