Best Answer

It depends on your the inclinantion of the plane which is used to "slice" the cone.

The answer can be a circle, ellipse, parabola, hyperbola or two intersecting lines. These (apart from the last) are known as conic sections.

In terms of the 2-d figure that generates a cone, the answer is a straight line, with a non-zero slope, rotated about the x-axis.

What is the name of a 2d cone?

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.


Does a cone have corners?

A cone is a 3D shape and corners are on 2D shapes. A cone has one vertex and one round edge. Corners are for 2D objects. A Triangle has three corners. I'll make things a bit clearer. No. thats it


What is the difference between a triangle and a cone?

A triangle is 2D, and has a square base. A cone is 3D, and has a circular base.


How do you find perimeter of a cone?

What is a cone vs prism?

A prism is an elongated 2D shape, while a cone is elongated, just shrinking as it gets to the tip. A cone has a curved surface, while a prism is composed of flat surfaces.


Does a cone have angles?

A cone has one vertex. The "size" of this vertex is known as the cone's opening angle.So the answer is sort of, but you can't count angles of a 3D shape in the same way as a 2D one.


What is the 2d shape for a cone?

If you look down from the top, it is circular. From the bottom, it is circular. From the side, it is a triangle.
