What is the name of a 2d cone?

Answer 1

A 2D cone is often referred to as a "conic section." In mathematics, a conic section is a curve obtained by intersecting a cone with a plane. The different types of conic sections include circles, ellipses, parabolas, and hyperbolas, each with unique properties and equations.

Answer 2

Oh, dude, a 2D cone is technically called a "conic section" or more specifically, a "2D cone shape" in geometry. It's like a flattened cone, you know, because it's in two dimensions instead of three. So, if you ever need to impress someone at a super nerdy party, just drop the term "conic section" and watch them be amazed.

Answer 3

A 2d cone is called a Light Cone.

<edit: Isn't it called a circle sector?>
