there are seven lines of reflection across which the regular polygon abcdefg can reflect to map onto itself. one of them is a
of

Explanation:

Step1: Properties of regular polygons

A regular polygon has lines of symmetry. For a regular \(n -\)sided polygon, the number of lines of symmetry is \(n\). A regular heptagon (\(n = 7\)) has \(7\) lines of symmetry.

Step2: Types of lines of symmetry

One type of line of symmetry for a regular polygon is the perpendicular bisector of its sides. Another is the line passing through a vertex and the mid - point of the opposite side (which can be a diagonal in some cases). For a regular heptagon \(ABCDEFG\), one of the lines of reflection (symmetry) is a perpendicular bisector of a side.

Answer:

perpendicular bisector
