Here my dog "Flame" has actually her face made perfect symmetrical through 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), climate the fold line is a line of Symmetry.
Here I have folded a rectangle one way, and it didn"t work.
But when I shot it this way, that does work (the folded component sits perfect on top, all edges matching):
A Triangle can have 3, or 1 or no currently of symmetry:
|Equilateral Triangle(all political parties equal, all angle equal)||Isosceles Triangle(two political parties equal, two angles equal)||Scalene Triangle(no political parties equal, no angle equal)|
|3 lines of Symmetry||1 heat of Symmetry||No present of Symmetry|
Different species of square (a 4-sided plane shape):
|Square(all political parties equal, all angles 90°)||Rectangle(opposite political parties equal, all angles 90°)||Irregular Quadrilateral|
|4 lines of Symmetry||2 currently of Symmetry||No currently of Symmetry|
|Kite||Rhombus(all sides equal length)|
|1 heat of Symmetry||2 present of Symmetry|
A continual polygon has actually all sides equal, and also all angles equal:
|An Equilateral Triangle (3 sides) has 3 lines of Symmetry|
|A Square (4 sides) has 4 present of Symmetry|
|A Regular Pentagon (5 sides) has 5 currently of Symmetry|
|A Regular Hexagon (6 sides) has 6 present of Symmetry|
|A Regular Heptagon (7 sides) has 7 currently of Symmetry|
|A Regular Octagon (8 sides) has 8 present of Symmetry|
And the sample continues:A consistent polygon that 9 sides has 9 lines of SymmetryA constant polygon that 10 sides has actually 10 lines of Symmetry...A continual polygon the "n" sides has actually "n" present of Symmetry
