which figure does not have reflectional symmetry?

Explanation:

Reflectional symmetry means a figure can be divided by a line (axis of symmetry) into two mirror - image halves.

• The first figure (a hexagon - like shape) has a vertical line of symmetry.
• The second figure (an equilateral triangle) has three lines of symmetry.
• The fourth figure (a regular octagon - like shape) has multiple lines of symmetry.
• The third figure (a scalene triangle - like shape) has no line that can divide it into two mirror - image halves.

Answer:

The third figure (the scalene - looking triangle) does not have reflectional symmetry.
