"The book has a diagonal black stripe on the cover."

Hello everyone, what does "diagonal black stripe" mean?

Thanks

It means that the stripe runs in one of two ways: 1) From the top left corner to the bottom right corner. or 2) From the top right corner to the bottom left corner.

Not necessarily from corner to corner.

These tops have a diagonal stripe.

It's still possible to locate the ends of each diagonal as being nearest to a "corner" even if we have to superimpose the image of a square or rectangle over the object that contains the diagonal.

If a book cover has a shape of square, that could be OWl's situation, right?

That's right, Silver. Either the stripe runs directly from one corner to another, or it starts near one corner and ends near another.

If we are talking about mathematics, a diagonal goes from corner to corner.

However, in non-mathematical contexts, a stripe at something like 45 degrees across an oblong shape, or a shield, &c, would still be called "diagonal".
