X-axis is lonely,
Y-axis is lovely;
When two of them form a right angle,
They have built a plane, solid like a triangle.
X-Y plane is strong but flat,
soon they begin to dream of something more than that;
Z-axis is lonely,
XY-plane is lovely,
When three of them work together to form a family,
They constitute a beautiful space in geometry.
Thus, x-axis is cute,
xy-plane is cuter,
and xyz cubic space is the cutest.
please look at the graphs above,
Enjoy a good laugh!
Life is no fun without z,
you got to learn you a-b-c!
