how many lines of symmetry has an equilateral triangle
a trapezium
Parallelogram.
A rhombus is a quadrilateral that has no line of symmetry but has rotation symmetry. Rotation symmetry means that the shape can be rotated by a certain degree and still look the same. In the case of a rhombus, it has rotational symmetry of order 2, meaning it can be rotated by 180 degrees and still appear unchanged.
no shape does! * * * * * Not true. A parallelogram has rotational symmetry of order 2, but no lines of symmetry.
Rotational symmetry is based on points of rotation not lines

The type of quadrilateral Francesca describes is a kite. A kite has rotational symmetry of order 2, meaning it looks the same when rotated 180 degrees, but it does not possess any lines of symmetry. This is due to the unequal lengths of its adjacent sides, which prevents it from being divided into two identical halves along any line.
