Here mine dog "Flame" has actually her challenge **made perfect symmetrical v a bitof picture magic.**

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

When the folded part sits perfectly on peak (all edges matching), then the fold line is a line of Symmetry.

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

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

But once I try it this way, it **does work** (the folded part sits perfectly 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 political parties equal, all angle equal) | Isosceles Triangle(two political parties equal, 2 angles equal) | Scalene Triangle(no sides equal, no angles equal) | ||

3 present of Symmetry | 1 heat of Symmetry | No present of Symmetry |

## Quadrilaterals

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

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

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

Kite | Rhombus(all sides same length) | |

1 line of Symmetry | 2 present of Symmetry |

## Regular Polygons

A continual polygon has all political parties equal, and all angles 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 currently 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 currently of Symmetry |

And the pattern continues:

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

**9**lines of SymmetryA continual polygon the

**10**sides has actually

**10**lines of Symmetry...A consistent polygon that

**"n"**sides has

**"n"**currently of Symmetry
