Can a regular heptagon tessellate a plane with no overlaps or gaps

I say No,but i want to be sure.

No. The largest regular polygon that you can use to tessellate a plane is, unsurprisingly, a square.Go beyond that, say, a regular pentagon, and you'll have gaps - that you could probably fill in with smaller pentagons, but you'd still have gaps. I know there's a more mathematical answer to this question - having to do with the internal angles of the polygon, etc. But I'd rather not stray from what I know and I'll leave it at that.
