When a guest
They will how many sides it has on

There is a shape four sides, so it's a square
And the one who has is looking fine
And its is Nonagon

Everybody turns in time to see the pentagon arrive
Counting up the sides, it is clear the pentagon has
Chatting in the we see

There is a triangle sides number three
And is talking to the shape has nine

Its name is Octagon and its add up to eight
Turning the on is a six sided hexagon
And they all get in a and do
A dance called, Nonagon
