If we label them A B C D E, then A is already connected to B & E, so
A-C, A-D: 2, Then B to D & E: 2, Then C to E (already to A): 1, then D is already connected to all of them, so 2 + 2 + 1 = 5, and you have a 5 pointed star.
In a pentagon, there are 5 corners (or vertices). To connect each corner to every other corner, you can use the formula for combinations, specifically ( C(n, 2) ), where ( n ) is the number of vertices. For a pentagon, this results in ( C(5, 2) = 10 ) lines needed to connect each vertex to every other vertex.
5 straight lines are needed to construct a pentagon.

A geometric star with five lines of symmetry is made by connecting the corners of an equal length sided pentagon. Since the pentagon has five equal sides, each line connecting the vertices (corners) will also be equal in length. Not equal however, to the sides of the pentagon. It is also called a pentagram.It is also a polygon.
draw four lines the make 3 right angles but don't connect at the end continue to finish the pentagon with whatever lines you want

Vertices are points (corners) and edges are lines that connect vertices
A pentagon has no parallel lines.

There are 5 lines of symmetry in a regular pentagon but a less amount in a irregular Pentagon
No lines are parallel in a regular pentagon.
