Let's talk about what is a regular heptagon first. A regular polygon is something with all equal sides and all equal angles, a heptagon as 7 sides, and all the interior angles are the same. Okay, let's get this over with. I don't know what I know about symmetries. I don't know what I could do to create lines of symmetry. It's a heptagona with an odd number of sides, so I can cut it in half. It will travel through the center of the opposite side. There's an odd number of sides in the middle of a line of symmetry, so it won't go through 2 mid points or 2 vertices, and I can do many other lines of symmetry there. What about reflectional symmetry. When do it reflect itself? It will reflect on itself a number of 123. If I have my center in the middle, it will reflect on itself seven times because it's all equal sides and on equal angles. It doesn't have 1 line of reflection. Since it's rotating about 51.43 degrees, every 51.43 degrees of it rotates on to itself, it has a multiple that has seven fold reflectional symmetry.
Which statements are true about the reflectional symmetry of a regular heptagon? Select two options. It has only 1 line of reflectional symmetry. A line of symmetry will connect 2 vertices. A line of symmetry will connect a vertex and a midpoint of an opposite side. It has 7-fold symmetry. A line of symmetry will connect the midpoints of 2 opposite sides.
