Answer:
The given statement:
Only regular polygons with an even number of sides are symmetrical is a FALSE STATEMENT.
Explanation:
A symmetrical figure or a polygon means that if it is into halves such that the halves looks similar or match exactly then the figure is said to be symmetrical.
We know that a regular polygon with 'n' number of sides has exactly n number of axis of symmetry.
Hence, no matter whether the regular polygon has even number of sides or odd number of sides it will be symmetrical.
