Question

only regular polygons with an even number of sides are symmetrical.

a. true

b. false

Explanation:

A regular polygon, regardless of whether the number of its sides is even or odd, has rotational and (for most) line symmetry. For example, an equilateral triangle (3 sides, odd) has 3 lines of symmetry and rotational symmetry of order 3. So the statement "Only regular polygons with an even number of sides are symmetrical" is incorrect.

Answer:

B. False
