- Edges are the line segments that join two vertices. Almost all the 2d and 3d shapes have straight edges. But a few shapes like hemispheres, cones, etc., have curved edges.

Nov 5, 2018 · When you talk about a cone or cylinder, you have to either use a different set of words, since "edge" and "vertex" as defined don't apply at all, and "face" applies only to one of the two surfaces of a cone; or you have to modify the definitions to allow curved edges and faces.
Jul 16, 2019 · The properties of 3D shapes are faces, edges and vertices. Faces are the flat or curved surfaces that make up the outside of a 3D shape. Edges are the lines where two faces on a 3D shape meet. Vertices are the corners of a 3D shape formed where two or more edges meet. For example, a cube has 6 faces, 12 edges and 8 vertices.
Vertices, Faces and Edges are the three properties that define any three-dimensional solid. A vertex is the corner of the shape whereas a face is a flat surface and an edge is a straight line between two faces. 3d shapes faces, edges and vertices, differs from each other.
- Vertices are the corners of the three-dimensional shape, where the edges meet. Faces are flat surfaces and edges are the lines where two faces meet.
- A cone has one flat surface and one curved surface. Therefore, it has only one edge where both the surface meet. It has a curved edge.
- A cube has 8 vertices.
- A triangular prism has 5 faces, 6 vertices and 9 edges.
- A cuboid has 6 faces.
Our page on Polygons covers shapes made with straight lines, also known as ‘plane shapes’. This page explains more about shapes with curves, especially two-dimensional ones. Two-dimensional curved shapes include circles, ellipses, parabolas, and hyperbolas, as well as arcs, sectors and segments.
3D shapes have faces (sides), edges and vertices (corners). Faces - A face is a flat or curved surface on a 3D shape. For example a cube has six faces, a cylinder has three and a sphere...
The common names of these shapes are cube, cuboid, cone, cylinder and sphere. 3D shapes are defined by their respective properties such as edges, faces, vertices, curved surfaces, lateral surfaces and volume. We come across a number of objects of different shapes and sizes in our day-to-day life.
No, all shapes don’t need to have straight lines for edges. Shapes like a hemisphere can have a curved edge.
