Answer:
Explanation:
We have to find which type of Regular Polygons are symmetrical.
Regular Polygons are the polygons whose all sides and angles are equal.
For ex:- Equilateral triangle is a regular triangle as its all sides are equal and all angles are equal to 60°.
Square is a regular quadrilateral whose all sides are equal and all angles are equal to 90°.
Option A:
Even-sided regular polygons are the polygons whose no of sides is an even no.
ex, quadrilateral with 4 side, hexagon with 6 sides.
They are symmetrical which no of line of symmetry equal to no of side.
Option B:
Odd-sided regular polygons are the polygons whose no of sides is an Odd no.
ex, Triangle with 3 side, pentagon with 5 sides.
They are symmetrical which only 1 line of symmetry.
Option C:
Rectangular regular polygons are also symmetrical.
Therefore, Option D is correct .i.e., ALL regular polygons are symmetrical.
