Question

select the correct answer from each drop - down menu.
there are seven lines of reflection across which the regular polygon abcdefg can reflect to map onto itself. one of them is a
(there are some drop - down options here which are not fully shown)
(and there is a diagram of the regular heptagon abcdefg with vertices labeled a, b, c, d, e, f, g in order)

Explanation:

Step1: Recall the property of regular polygon

A regular \(n -\)sided polygon has \(n\) lines of reflection.

Step2: Identify the number of sides

The given polygon \(ABCDEFG\) is a heptagon (a \(7 -\)sided polygon).

Step3: Determine the number of lines of reflection

For a regular heptagon, the number of lines of reflection across which it can map onto itself is equal to the number of its sides.

Answer:

\(7\)
