Cutting a cone at any angle

Robin07

I was taught that if you cut through a cone at any angle you will end up with a circle shape at the cones edge. Is this true?

Your question isn't clear. But taking a guess at your meaning, it is false,. You can end up with any conic section. That's where the name "conic section" comes from.

Thanks for the terminology. I looked it up on wikipedia which cleared things up .

Thanks again.
