A cone has 1 edge.
Understanding Edges in Geometric Shapes
In geometry, an edge is a particular type of line segment joining two vertices (corners or points where lines meet) in a geometric shape. It's a fundamental concept for understanding the structure and properties of these shapes.
Examining the Cone
A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (which can be a circle or an ellipse) to a point called the apex or vertex.
- The cone's curved surface connects the base to the apex.
- The base of a cone is a circle, and its circumference acts as a single edge on the cone.
- The point where the circular base and the cone surface connect is not an edge in itself. It constitutes a smooth transition, not an edge or corner.
Edges in a Cone
According to the provided reference, a cone has only one edge. The edge is the circular line that defines the cone's base.
Summary
| Shape | Number of Edges |
|---|---|
| Cone | 1 |
Therefore, the final answer remains that a cone has only one edge, the circular base.
