3. What is Symmetry? An image has Rotational Symmetry if there is a center point around which the object is turned a certain number of degrees and the object still looks the same. An equilateral triangle has 3 internal angles and 3 lines of Symmetry. A square has 4 internal angles, and 4 lines of symmetry. A regular pentagon has 5 internal angles and 5 lines of symmetry. A regular hexagon has 6 internal angles and 6 lines of Symmetry. A regular octagon has 8 internal angles and 8 lines of Symmetry. A shape has line symmetry when one half of it is the mirror image of the other half

6. Nature and Line Symmetry

7. Road signs and Symmetry Order 1+1 line of symmetry Order 2+1 line of symmetry Order 2+0 line of symmetry Order 2+1 line of symmetry Order 4+4 lines of symmetry

8. Monuments and Symmetry Symmetry exists in architecture all around the world. On of the best known example of this is the Taj Mahal. If an object is reflected in water many people believe that the image has line symmetry. But it is really a “mirror image”.
