Maths: Sometimes, always, never....?

A shape with four sides is called a quadrilateral

Is this sometimes true?
Always true? or
Never true?

Explain your answer

A two dimensional shape with four straight sides and four angles is a quadrilateral. It might also be other things - Someone might look at a four-sided shape with equal sides but no right-angles and call it a rhombus, for example. In that sense, quadrilaterals are not always called quadrilaterals by those who view them.

And as you hint a 3 d shape is never called a quadrilateral.

3D shapes don't even have sides.

I’m 3D, i’m a shape (albeit not a pretty one) and my side is Arsenal.

It must be a 2D shape as three dimensional shapes have faces and edges not sides
