Step 2: Extend the line segment in the same direction and by the … WebIt does change, but depends more on if the polygon is regular or not. If a polygon is irregular, chances are there will be less lines of symmetry. An equilateral triangle will have 3 lines of symmetry, but a scalene triangle will have none. If a polygon is regular, the number of sides it has is the amount of symmetry lines it will have.
