Symmetry: Lines, Reflection, Rotation
Objectives: Find co-ordinates of points determined by geometric information. Understand and use the language and notation of reflections. Recognise.
FeatureLesson Geometry Lesson Main Tell what type(s) of symmetry each figure has. 1.D 2.O reflectional: horizontal line of symmetry reflectional: horizontal.
Symmetry: A Visual Presentation. Line Symmetry A shape has line symmetry when one half of it is the mirror image of the other half. A shape has line symmetry.
Rotational Symmetry If, when you rotate a shape, it looks exactly the same as it did in its original position, then we say that the shape has got rotational.
Rotational Symmetry Rotational Symmetry If, when you rotate a shape, it looks exactly the same as it.
