Symmetry: A Visual Presentation
Line Symmetry n Shape has line symmetry when one half of it is the mirror image of the other half. n Symmetry can have vertical, horizontal or diagonal line symmetry.
Is a butterfly symmetrical?
Line Symmetry exists in nature but you may not have noticed.
At the beach there a variety of shells with vertical line symmetry.
Under the sea there also many symmetrical objects such as these crabs. They have horizontal symmetry. This starfish has vertical and diagonal symmetry.
Animals that have Line Symmetry Here a few more great examples of vertical symmetry in the animal kingdom.
THESE MASKS HAVE SYMMETRY These masks have a line of symmetry from the forehead to the chin. The human face also has a line of symmetry in the same place.
REFLECTION IN WATER If an object is reflected in water it is considered to have line symmetry along the waterline. This is called horizontal symmetry.
The Taj Mahal Symmetry exists in architecture all around the world. The best known example of this is the Taj Mahal.
This photograph shows 2 lines of symmetry. One vertical, the other horizontal along the waterline. (Notice how the prayer towers, called minarets, are reflected in the water and side to side).
2 D Shapes and Symmetry Let’s look at 2 D shapes to find lines of symmetry.
How many lines of symmetry did you find for each shape?
An equilateral triangle has 3 lines of symmetry.
A square has 4 lines of symmetry.
A regular pentagon has 5 lines of symmetry.
A regular hexagon has 6 lines of symmetry.
A regular octagon has 8 lines of symmetry.
Let’s do a practice problem together: n Lisa and Rob are flying a rhombus shaped kite. They need to fold the kite in half along a line of symmetry to have it fit in a backpack. Which picture shows the lines they can choose from? A B C D
