Nonagon

Everybody at the party is a many sided polygon

When a guest arrives

They will count how many sides it has onStanding by the window over there

There is a shape with four sides, so it's a square

And the one who has nine is looking fine

And its name is NonagonEverybody turns just in time to see the pentagon arrive

Counting up the sides, it is clear the pentagon has five

Chatting in the kitchen we seeThere is a triangle whose sides number three

And is talking to the shape that has nine

Who is known as NonagonNonagonNonagon, lets in a guest who has shown up late

Its name is Octagon and its sides add up to eight

Turning the music on is a six sided hexagon

And they all get in a line and do

A dance called, 'the NonagonThe Nonagon

The Nonagon
