Which statements are true about the reflectional symmetry of a regular heptagon? check all that apply. 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.

A line of symmetry will connect a vertex and a mid point of an opposite side, it has 7 fold symmetry.

Step-by-step explanation:

When the figure can be folded over onto itself along a line. This line is called the "line of symmetry" and this exists for the rotational symmetry.

If we connect a vertex and a midpoint of an opposite side of an heptagon by drawing a line, we will obtain two equal halves.

Also, a heptagon has seven vertices, therefore it has 7 fold symmetry.
