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.

The answer is:

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

2- It has -fold symmetry.

The explanation for this answer is shown below:

1- By definition, a line of symmetry is an imaginary line that divides a figure into two equal images or equal halves. If you connect a vertex and a midpoint of an opposite side of an heptagon by drawing a line, you will obtain two equal halves.

2- An heptagon has seven vertices, therefore, based on the information mentioned above, it has -fold symmetry.

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
