A star is not a specific shape: it is a generic word for a shape which has an even number of vertices. The interior angles at alternate vertices are usually reflex angles. A star can have six or more vertices.

A star has 10 vertices. The way to find this is a regular star has 5 vertices. And 5x2 = 10, right?
A geometrical star can have various numbers of vertices, and the angles formed at the vertices need not be the same. The number of perpendicular lines depends on exactly how many vertices it has and how their angles are configured.
A pentagram is a five pointed star and has 10 vertices. So, a pentagram prism has 20 vertices. This is NOT the same as a pentagonal prism.
