3.
You need at least three faces. Four faces meeting at a vertex will form a plane (360 deg), 5 or more will make the shape concave (rippled) at that vertex.

What is the measure of one angle of a regular convex 80 gon?
Exterior angle = 360/80 = 4.5 degrees. Interior angle = 180 - 4.5 = 175.5 degrees. And, a regular polygon has to be convex.
