GL Pack 2 Maths Paper 6 Q 9

[gulat]

There is a question on GL Pack 2 Paper 6 where a few reular polygons are drawn and it is asked which one will fit such that no space is remaining. The answer sheet provides teh answer as 'd'. Can someone please explain why 'd'? So close to the exams I am sure I am missing something obvious

Many thanks in advance

I think it is because the vertices that would meet at a point would add up to 360 degrees - sorry have not got the question in front of me but think I remember the one that you mean. That wasn't a great explanation of mine but I hope you get my drift.
