A cone is a three-dimensional solid with one flat, circular base and one curved surface that narrows to a single point, called a vertex; its orientation does not change its identity. Recognizing these defining features helps distinguish cones from cylinders, spheres, and pyramids, without requiring measurement of radius or height, formulas for volume, nets, or more advanced classifications.

Detailed Explanation: Identify cones
A cone is a solid shape with:
- one flat, circular base
- one curved surface
- a curved surface that narrows to one point, called the vertex
A cone can point up, down, or sideways. Its position does not change its shape.
Example: Which object is a cone: a party hat, a soup can, or a ball?
- Look at the party hat. It has a flat, round opening at the bottom.
- Its sides are curved and get smaller.
- The sides meet at one point at the top.
- So, the party hat is a cone.
A soup can has two circular ends and does not come to a point. A ball has no flat circular base.
