L.O – To be able to find the number of lines of symmetry and the order of rotational symmetry for a wide range of shapes
Line Symmetry :
A line of symmetry divides the shape into two equal parts.
Each part is a reflection of the other.
If a shape is folded along it’s line of symmetry each part fits exactly on top of the other.
Remember, a regular polygon has the same number of lines of symmetry as it has sides
Rotaional Symmetry :
This is where you can rotate the shape into different positions that all look the same
A shape has rotational symmetry if it fits on top of itself more than once as it makes a complete turn.
The order of rotational symmetry is the number of times that the shape fits on top of itself. This must be 2 or more.
The “centre of rotation” is the point about which the shape turns.
Remember, a regular polygon has the same order of rotational symmetry as it has sides.
Draw all the lines of symmetry onto these shapes and write down the order of rotational symmetry.
Pick out the shapes with
- only one line of symmetry
- rotational symmetry of order 2
Mark with a cross the centre of rotation.
Shade one more square to make a pattern with one line of symmetry
Shade one more square to make a pattern with
rotational symmetry of order 2
