A parallelogram has rotational symmetry. A parallelogram does not have reflectional symmetry. The easiest way to do this is to draw a point in the middle of the shape and rotate it to see if the point looks the same from all angles.

What type or types of quadrilateral has only rotational symmetry?

The quadrilateral would have to be a parallelogram which is not also a rectangle or a rhombus.


What is the minimum angle of rotational symmetry for the quadrilateral?

The minimum angle of rotational symmetry for a quadrilateral is 90 degrees. This means that if you rotate the quadrilateral by 90 degrees around its center, it can align with its original position. However, a general quadrilateral does not have rotational symmetry unless it is a special type, such as a rectangle or a square. In those cases, the symmetry can be 90 degrees or less, with a square having 90 degrees and a rectangle having 180 degrees.

Francesca describes a type of quadrilateral. it has rotational symmetry of order 2 but it has no lines of symmetry.?

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.

Equilateral triangles have rotational symmetry.


What type of triangle has only line symmetry and no rotational symmetry of order more than 1?

A scalene triangle has only line symmetry and no rotational symmetry of order more than 1. In a scalene triangle, all sides and angles are different, preventing it from having any rotational symmetry. It may have at most one line of symmetry if it has a specific arrangement or reflection, but generally, it lacks line symmetry entirely.

Which quadrilaterals always have both line symmetry and rotational symmetry?

The quadrilaterals that always have both line symmetry and rotational symmetry are squares and rectangles. Squares have four lines of symmetry and rotational symmetry of order 4, while rectangles have two lines of symmetry and rotational symmetry of order 2. Other quadrilaterals, like rhombuses and parallelograms, may have one type of symmetry but not both. Thus, squares and rectangles are the only quadrilaterals that consistently possess both symmetries.
