The lines inscribed as directed will result in a "star" being formed inside, and a pentagon will be formed in the middle of the star. The pentagram will have been separated into 11 regions by inscribing it as directed.
The vertex of a 3D pentagon is 10. :)

A vertex is a corner or a point where lines meet. Those lines are called rays or segments.
This is the vertex of the angle between the two line segments
if you did not know the answer would be a pentagon.
If divided by a vertex-to-vertex line, it is an isosceles trapezium. If divided by a line from one side to the opposite side, it will make an irregular pentagon.

The vertex of a 3D pentagon is 10. :)
Pentagon
If you want it divided into five equal parts, draw a dot in the center of the pentagon, and draw a line form each vertex to the dot. You should now have five equal triangles.
In a regular pentagon, the lines of symmetry are drawn from each vertex to the midpoint of the edge directly opposite the vertex, so there are five in all.
You can find a vertex wherever two lines (or line segments) meet.
Five vertices.
1 vertex less than a hexagon is a pentagon. 2 angles more than a triangle is a pentagon.
