Rudolph the parallelogram
Had 2 sets of parallel sides
And if you ever saw him
Can you guess what you would find?

If all his sides are equal
A rhombus, that would be his name
And if he is rectangular
All his angles are the same

All of the little trapezoids
Used to laugh and call him names
"Rudolph the Parallelogram,
You know that we are not the same!"
