Construction of a Regular Dodecahedron

Arrange 5 congruent regular pentagons around a central one. Each of the outer 5 pentagons shares a side with the center pentagon.

By folding the extensions on the connecting bases, we can form the half of a regular Dodecahedron.

By duplicating this formation, rotating the duplicate 180°, then again around the vertical axis for 36°, and finally by connecting the two polyhedrons, we form a regular dodecahedron.
