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.
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
Diagonals connect corners of a figure. If you try to connect two corners of a three sided figure, the lines you draw will exactly mimic the sides of the figure. Because of this, a three sided figure has no diagonals.

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
