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.
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.

Polyhedron. It's any three-dimensional shape made up of flat faces, sharp edges (where two faces meet), and points (where three faces 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 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.
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.

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.
As long as they are not parallel, they will meet at an "edge", which is just a straight line.
edge
They are the one dimensional "lines" where the faces of the pyramid meet, in pairs.
