2d and 3 d

Said Tejas... We don't see any circle. They are spheres. They are 3d. Turn behind you see something so they are sphere.

Me...steering wheel?

Tejas- marks the thickness of it and says see it is not circle.

We conclude it is a ring.

Next question .
What is the 3d of triangle.
Seriously I forgot it is a prism.
We debated about pyramids but decided they are too big and triangle drawn on paper is very small plus a pyramid is not solid so decided against it.

Not very logical but so what. I can't know everything.
