Here mine dog "Flame" has her confront **made perfectly symmetrical through a bitof picture magic.**

**The white line down the center is theline of Symmetry**

When the folded component sits perfect on top (all edges matching), then the fold line is a heat of Symmetry.

Here I have actually folded a rectangle one way, and **it didn"t work**.

**So this is not**a line of Symmetry

But as soon as I shot it this way, that **does work** (the folded component sits perfect on top, every edges matching):

**So this is**a line of Symmetry

## Triangles

A Triangle can have **3**, or **1** or **no** lines of symmetry:

Equilateral Triangle(all political parties equal, all angle equal) | Isosceles Triangle(two political parties equal, 2 angles equal) | Scalene Triangle(no sides equal, no angles equal) | ||

3 currently of Symmetry | 1 heat of Symmetry | No lines of Symmetry |

## Quadrilaterals

Different varieties of square (a 4-sided airplane shape):

Square(all political parties equal, all angles 90°) | Rectangle(opposite sides equal, all angle 90°) | Irregular Quadrilateral | ||

4 currently of Symmetry | 2 lines of Symmetry | No present of Symmetry |

Kite | Rhombus(all sides equal length) | |

1 line of Symmetry | 2 currently of Symmetry |

## Regular Polygons

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

An Equilateral Triangle (3 sides) has 3 present of Symmetry | ||

A Square (4 sides) has 4 lines of Symmetry | ||

A Regular Pentagon (5 sides) has 5 lines of Symmetry | ||

A Regular Hexagon (6 sides) has 6 present of Symmetry | ||

A Regular Heptagon (7 sides) has 7 present of Symmetry | ||

A Regular Octagon (8 sides) has 8 lines of Symmetry |

And the sample continues:

**9**lines of SymmetryA constant polygon the

**10**sides has

**10**currently of Symmetry...A continuous polygon that

**"n"**sides has

**"n"**currently of Symmetry
