A triangle has 3 lines of symmetry.
parallelogram
a polygon
A square has four lines of symmetry!
How many lines of symmetry does the 15 side polygon have
Equilateral Triangles (3 lines of symmetry)Rectangles (at least 2 lines of symmetry)Squares (4 lines of symmetry)Rhombuses (at least 2 lines of symmetry)Any regular polygon (at least 5 lines of symmetry)
No, a polygon can have fewer lines of symmetry.
an irregular polygon
A triangle has 3 lines of symmetry.
Number of lines of symmetry = Number of sides of the regular polygon
parallelogram
A rectangle (that is not also a square) or a rhombus (that is not also a square). Squares have 4 symmetry lines.
10 lines. Regular polygon of "x" sides has "x" Lines of Symmetry
I think that it can have 0, 1, 2, 3, 6, 9 or 18 lines of symmetry.
a polygon
A 15 sided polygon has 15 lines of symmetry;) Thanks for asking:)
