Example of a transparent PNG:.

The question is though if your image editing program allows transparency. Microsoft Paint for instance, even when you save something as a PNG file, does not allow transparency.

But that's because Paint lacks the feature. Other programs, like GIMP, Photoshop and SAI, do support transparent PNGs. Ergo, whether or not a PNG can be transparent depends on the computer program you are using.

PS: your teacher mentioned that not everything on the internet is right, not that everything on the internet is wrong. Like books, internet can be both right or wrong.
