edge
When two sides (called faces) of a 3-dimensional shape meet, they meet at an edge.
They are the points where three (or more) planes (or faces of the shape) meet.
A line segment formed where two faces meet is called an edge. In three-dimensional geometry, edges are the straight lines that connect the vertices of a solid shape, defining the boundaries of its faces. Each edge serves as a structural component, contributing to the overall shape and form of the object. For example, in a cube, each of the twelve edges connects two vertices and forms the intersection between two adjacent faces.
In a 3-dimensional shape with polygonal faces, an edge is a straight line at which two faces meet. A vertex is a point where three or more edges meet. In solid shapes which are not polyhedra, an edge is still a line - possibly curved - where two faces meet. But a vertex can be any corner, for example, the point of a cone.

When two sides (called faces) of a 3-dimensional shape meet, they meet at an edge.
They are the points where three (or more) planes (or faces of the shape) meet.
Any 2-dimensional shape has a vertex where two sides meet.Any 3-dimensional shape has a vertex where three or more faces meet.
Three dimensional objects have edges, vertices and faces. A face is a plane surface which forms a boundary of the shape. Two faces meet along a line which is an edge. Three or more faces meet at a point which is a vertex.
A solid with smooth faces, sharp edges, and points is called a polyhedron. Examples of polyhedrons include cubes, pyramids, and prisms.
A pyramid with a square base is called a square pyramid. It is a three-dimensional shape that has a square as its base and four triangular faces that meet at a point called the apex.
A tissue box is typically in the shape of a rectangular prism, which is a three-dimensional shape with six faces, all of which are rectangles. The base and top faces of the tissue box are congruent and parallel, as are the side faces. The edges where the faces meet are all right angles.
A tetrahedron is a 3 dimensional shape bounded by 4 triangular faces. It has 4 vertices and six edges. Three faces meet at each vertex so that the shape is self-dual.
A line segment formed where two faces meet is called an edge. In three-dimensional geometry, edges are the straight lines that connect the vertices of a solid shape, defining the boundaries of its faces. Each edge serves as a structural component, contributing to the overall shape and form of the object.

For two dimensional shapes, a vertex (plural vertices) is a point where two sides meet.For 3D shapes, a vertex is a point where three or more faces meet.
