Three edges meet at each vertex.
The shape you are describing is a rectangular prism. A rectangular prism has 8 vertices, with each vertex connecting three edges. It also has 6 faces, with each pair of opposite faces being parallel to each other.
Each one of the five points.
There are 9 edges. It has three edges which are parallel to each other (along the length of the prism) AND it has three pairs of parallel edges - at the top and bottom of the prism.

No. For example, a cube is a polyhedron and 3 edges meet at each vertex.
Each point of a polygon at which two sides intersect is called VERTEX
Each one of the five points.
There are 9 edges. It has three edges which are parallel to each other (along the length of the prism) AND it has three pairs of parallel edges - at the top and bottom of the prism.

A triangular prism has 3 sides on each base (2) and 3 on the lengths of the prism therefore it has 9 edges.
A octagonal prism has 16 verticies,10 faces and 24 edges.
The orthocentre is a point within a triangle where the perpendicular of each vertex to its base intersect each other.
