Which of the following polygons has three lines of symmetry a. regular pentagon b. square c. regular hexagon d. equilateral triangle

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.

the answer is 175.4379
