Respuesta :
All of them have at least 3 lines of symmetry. But the one with only 3 lines of symmetry would have to be the equilateral triangle (d).
Answer:
D. Equilateral triangle
Step- by-step explanation:
Regular polygon is a polygon which has all the angles and sides are in the same measure.
The number of line of symmetry on the regular polygons depends upon the number sides.
Regular pentagon - which is 5 sided figure, so there will be five lines of symmetry.
Square - which 4 sided figure, so there will be four lines of symmetry.
Regular hexagon - which is 6 sided figure, so there will be six lines of symmetry.
Equilateral triangle - which is 3 sided figure all the sides and all the angles are in equal measure. There will be three lines of symmetry.
So, the answer is D. Equilateral triangle.
