[b][size=150][color=#ff0000]Symmetry[/color] is the key to the balance of a design or structure.[br][br]What is [color=#ff0000]symmetry[/color]? How does an image have [color=#ff0000]symmetry[/color]? What would you have to do to be sure that an image or construction was [color=#ff0000]symmetrical[/color].[br][br]In this concept, you will learn to identify lines of [color=#ff0000]symmetry[/color]. [/size][/b]

[b][size=150]Sometimes, an image will have parts that mirror themselves within one object. This is called [color=#ff0000]symmetry[/color][/size][/b]

[b][size=150]Let's look at the image of a heart above. It has two sides that match. The heart is [color=#ff0000]symmetrical[/color] because there is[color=#ff0000] symmetry[/color] in its design. This heart can be divided in half [color=#ff0000]vertically[/color] where one half matches the other half. [/size][/b]

[b][size=150]This line that divides the heart into matching parts is called the[color=#ff0000] line of symmetry[/color].[br][/size][/b]

[b]Look at the cross above. It has two lines of [color=#ff0000]symmetry. [/color] The cross can be divided in half perfectly [color=#ff0000]vertically [/color]and in half [color=#ff0000]horizontally[/color].[/b]

[b][size=150]This means there are two lines of[color=#ff0000] symmetry [/color]in the cross. [/size][/b]

[b][color=#0000ff][size=150][size=200]Does this image have symmetry? Can it be a reflection?[/size][/size][/color][/b]

[size=150][b][color=#0b5394]First, try to divide this butterfly image evenly so that one side can reflect the other. Can you draw a line of symmetry?[/color][/b][/size]

[size=200][b][color=#0000ff]The answer is yes. Therefore the image of the butterfly has symmetry. [/color][/b][/size]

[b][color=#ff0000][size=150][size=200]Does the image of the flower have symmetry? [/size][br]First, try to divide this flower evenly so that one side can reflect the other. Can you draw a line of symmetry? [/size][/color][/b]

[size=200][b][color=#cc0000]The answer is yes. Therefore, the image of the flower has symmetry. [/color][/b][/size]

[b][color=#ff7700][size=200]How many lines of symmetry does the image above have? [/size][/color][/b]

[size=150][b][color=#b45f06]First, try to divide this rectangle evenly so that one side can reflect the other. Can you draw a line of symmetry?[/color][/b][/size]

[size=200][color=#ff7700]The answer is yes. The image has two lines of symmetry. [/color][/size]
