What are Transformations? : What are Transformations? To reflect a shape means to fold or flip it over a line. Reflections (Flips)
Reflectional Symmetry/ LINE SYMMETRY : Reflectional Symmetry/ LINE SYMMETRY Shape has line symmetry when one half of it is the mirror image of the other half.

Slide 31 : How many lines of symmetry?
Shapes and Symmetry : Shapes and Symmetry Fold the following regular shapes to see how many lines of symmetry each has:
Triangle
Square
Pentagon
Hexagon
Octagon
Slide 33 : Equilateral Triangle
3 lines of symmetry
Slide 34 : Square
4 lines of symmetry
Slide 35 : Regular Pentagon
5 lines of symmetry
Slide 36 : Regular Hexagon
6 lines of symmetry
Slide 37 : Regular Octagon
8 lines of symmetry
What are Transformations? : What are Transformations? To turn a shape is to rotate it about a point a certain number of degrees. Rotations (Turns)
Rotational Symmetry:To Turn a shape is to rotate it about a point ! : Rotational Symmetry:To Turn a shape is to rotate it about a point !
Slide 40 : A triangle matches itself 3 times. It has rotational symmetry of Order 3 Rotational Symmetry - when you can turn an object & it matches up with itself.
