Question

1. which of the following figures does not have reflectional symmetry?

Explanation:

A figure has reflectional symmetry if there is a line (axis of symmetry) that can divide the figure into two congruent halves such that one half is the mirror - image of the other. The first figure (a non - isosceles trapezoid) has no such line. The second figure (a star) has multiple axes of symmetry. The third figure (a square) has 4 axes of symmetry.

Answer:

The first figure (the non - isosceles trapezoid).
