Here my dog "Flame" has her challenge made perfect symmetrical with a bitof photo magic.

The white line under the facility is theline of Symmetry

When the folded part sits perfectly on top (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 once I shot it this way, that does work (the folded component sits perfect on top, every edges matching):

So this is a heat of Symmetry

## Triangles

A Triangle have the right to have 3, or 1 or no present of symmetry:

 Equilateral Triangle(all sides equal, all angles equal) Isosceles Triangle(two political parties equal, two angles equal) Scalene Triangle(no political parties equal, no angle equal) 3 currently of Symmetry 1 heat of Symmetry No lines of Symmetry

Different species of quadrilateral (a 4-sided aircraft shape):

 Square(all sides equal, all angle 90°) Rectangle(opposite sides equal, all angles 90°) Irregular Quadrilateral 4 lines of Symmetry 2 lines of Symmetry No present of Symmetry

 Kite Rhombus(all sides equal length) 1 line of Symmetry 2 lines of Symmetry

## Regular Polygons

A continual polygon has all political parties equal, and also all angle equal:

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

And the sample continues:

A continual polygon that 9 sides has 9 currently of SymmetryA continuous polygon of 10 sides has 10 present of Symmetry...A constant polygon that "n" sides has "n" currently of Symmetry
