Question

Select all the polygons that have reflection symmetry.

A quadrilateral with two pairs of adjacent congruent sides, forming a kite.

A polygon is shaped like a composite figure made up of a rectangle with a small square on its top side and the same sized square on its right side.

A polygon shaped like a five-pointed star in which the left and right sides of the star are mirror images

A six-sided polygon that generally appears as a diagonally-oriented trapezoid attached to a shorter horizontally-oriented rectangle.

Answer 1

Reflection Symmetry-

Line symmetry is also called as the reflection symmetry. If, at least one line that divides a figure into two halves such that one-half is the mirror image of the other half, exists, then the figure is said to be in reflection symmetry.

Analyzing all the 4 figures, it can be deduced that only 1st and 2nd figures have one symmetry line XX, as shown in the attachments.

3rd and 4th figures do not have any axisymmetric lines, so they are not in reflection symmetry.
