Question

A heptagon has all equal side lengths.

Answer 1

Answer:

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

and

It has a 7 fold symmetry.

Step-by-step explanation:

I just took the test and I got it right, but I can still explain a lil bit. A line of symmetry is basically a line that splits a shape evenly. It's like folding a paper in half, it has perfect symmetry. A vertex is a point where two or more curves, lines, or edges meet and a midpoint is the point on a line segment or an arc that is equidistant, when measured along the line or the arc, from both endpoints.  If the two vertexes are symmetric, they will have the same midpoint. The 7 fold symmetry answer is easy to prove because you literally just count the sides of the shape you are working with and that will tell you the fold.

Hope this makes sense and helps :)
