Answa line of symmetry will connect a vertex and a midpoint of an opposite side

it has 7-fold symmetry.  

Step-by-step explanation:

A line of symmetry is a line that we can use to "fold" a figure in half. In order to do this, we will "fold" the figure from a vertex to the middle of the side opposite the vertex. Since there are 7 vertices, there will be 7 lines of reflection. i looked it up so i hope this helps you can thank
