Here my dog "Flame" has actually her face **made perfectly symmetrical through a bitof photo magic.**

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

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

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

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

But when I shot it this way, the **does work** (the folded part sits perfectly on top, all edges matching):

**So this is**a line of Symmetry

## Triangles

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

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

3 present of Symmetry | 1 line of Symmetry | No currently of Symmetry |

## Quadrilaterals

Different species of square (a 4-sided plane shape):

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

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

Kite | Rhombus(all sides equal length) | |

1 heat of Symmetry | 2 present of Symmetry |

## Regular Polygons

A continuous polygon has all political parties equal, and all angle 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 present of Symmetry | ||

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

And the pattern continues:

A consistent polygon of**9**sides has actually

**9**lines of SymmetryA regular polygon of

**10**sides has actually

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

**"n"**sides has

**"n"**present of Symmetry
