How many sides does a vertices have?

Answer 1

This question does not make sense. First of all, "vertices" is the plural of "vertex", but you have used it in a singular context, which suggests that you don't know what the word means. Second, a vertex is a point, so it cannot have sides. The answer to the question might be "zero", but it's equally likely that several important words have been omitted from the question. If the question were written correctly, it could change both the question and the answer, entirely.
