The circle is a shape
That's easy to be found.
It has no corners on it.
And is completely round.
The triangle is a simple shape,
I think you will agree.
Count its sides and corners
And you will find just three.
Here's a shape that you should know,
A square has its name.
It has four corners and four sides
That measure all the same.
This shape is called a rectangle,
It's found most everyhwere.
It has four corners and four sides,
Sort of like a square.
But if you call this shape a square,
You would be very wrong.
Since two of its sides are short
And two of them are long.
