A rhombus which has at least one angle a right angle (i.e. a square which is a special type of rhombus)
A rhombus
Yes. A rhombus has a 180 degree rotational symmetry but no reflection symmetry.
Because a rhombus which is rotated through 180 degrees will coincide with itself.
Rhombus has an 180 degree rotational symmetry, but no reflectional symmetry. Ps. i roll for my black men
Four, if the quadrilateral is a square, but if it is a rectangle it only has two and if it is an irregular quadrilateral it most probably only has one. So a rectangle, a rhombus, and a parallelogram have two, orders of rotational symetry but a kite and a trapezium although quadrilaterals (4sides) only have one.
both
order two
Yes, of order 2.
A rhombus
Yes. A rhombus has a 180 degree rotational symmetry but no reflection symmetry.
A rhombus is a polygon. A rhombus is a 4 sided shape and an 'equilateral quadrilateral' (all sides are the same length). Opposite angles are equal in a rhombus. A rhombus can tessellate. A rhombus has two lines of symmetry, joining its opposite corners. A rhombus also has rotational symmetry. A kite is a rhombus, and has rotational symmetry of both 180 degrees as well as 360 degrees, A rhombus is not a regular polygon as all angles have to be congruent for it to be classed as regular.

It has rotational symmetry order 2. Its is also known as a diamond and is a special type of rectangle
Yes, of order 2.
A rhombus is one example.
Yes a rhombus has 2 lines of symmetry. These lines of symmetry join its opposite corners.
