Symmetry
Line symmetry and rotational symmetry.
Square
Lines of symmetry = 4
Order of rotation = 4
Order of rotation is the
number of ways a shape will
look exactly the same during
one full turn
Equilateral triangle
Lines of symmetry = 3
Order of rotation = 3
Parallelogram
Lines of symmetry = 0
Order of rotation = 2
Rectangle
Lines of symmetry = 2
Order of rotation = 2
Isosceles triangle
Lines of symmetry = 1
Order of rotation = 1
Isosceles trapezium
Lines of symmetry = 1
Order of rotation = 1
Rhombus
Lines of symmetry = 2
Order of rotation = 2

Triangles
A triangle has 3 straight sides.
Isosceles
Two sides are the same and
two angles are the same.
Equilateral
All sides are the same and
all the angles are the same.
All angles are 60°.
Scalene
No sides or angles are
the same size.
Right-angled
One angle is 90°.
