Here my dog "Flame" has actually her confront made perfect symmetrical v a bitof photograph magic.

The white line under the facility is currently of Symmetry

When the folded part sits perfect on optimal (all edge matching), then the wrinkles line is a heat of Symmetry.

Here I have folded a rectangle one way, and it didn"t work. So this is not a heat of Symmetry

But as soon as I try it this way, that does work (the folded component sits perfect on top, all edges matching): So this is a line of Symmetry

## Triangles

A Triangle can have 3, or 1 or no currently of symmetry:  Equilateral Triangle(all political parties equal, all angles equal) Isosceles Triangle(two sides equal, two angles equal) Scalene Triangle(no political parties equal, no angle equal) 3 lines of Symmetry 1 line of Symmetry No present of Symmetry

Different species of quadrilaterals (a 4-sided aircraft shape):  Square(all political parties equal, all angles 90°) Rectangle(opposite sides equal, all angle 90°) Irregular Quadrilateral 4 present of Symmetry 2 lines of Symmetry No currently of Symmetry  Kite Rhombus(all sides same length) 1 line of Symmetry 2 present of Symmetry

## Regular Polygons

A continuous polygon has actually all sides equal, and also all angles equal:

 An Equilateral Triangle (3 sides) has 3 currently of Symmetry A Square (4 sides) has 4 currently of Symmetry A Regular Pentagon (5 sides) has 5 present of Symmetry A Regular Hexagon (6 sides) has 6 currently of Symmetry A Regular Heptagon (7 sides) has 7 currently of Symmetry A Regular Octagon (8 sides) has 8 present of Symmetry

And the pattern continues:

A regular polygon of 9 sides has 9 lines of SymmetryA consistent polygon that 10 sides has 10 present of Symmetry...A regular polygon the "n" sides has actually "n" present of Symmetry
