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. :)
To inscribe a pentagon in a circle, first, draw a circle using a compass. Then, mark five equally spaced points on the circumference, which can be done by dividing 360 degrees by 5, resulting in 72-degree segments. Connect these points with straight lines to form the pentagon. Ensure that each vertex touches the circle, confirming that the pentagon is inscribed.

A regular pentagon has five lines of symmetry. Each line of symmetry passes through one vertex and the midpoint of the opposite side. This symmetry allows for the pentagon to be divided into mirror-image halves along these lines.
To construct a pentagonal pyramid, you need a pentagon as the base polygon. The pyramid is formed by connecting each vertex of the pentagon to a single apex point above the center of the pentagon. This creates five triangular faces, each formed by one edge of the pentagon and two segments connecting the apex to the endpoints of that edge. Thus, the basic polygons involved are one pentagon and five triangles.
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.

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.
Five vertices.
1 vertex less than a hexagon is a pentagon. 2 angles more than a triangle is a pentagon.
You can find a vertex wherever two lines (or line segments) meet.
