What is a symmetrical polygon?
As the name suggests, they are polygons that have one or more lines of symmetry or rotational symmetry of order two or more. A symmetric polygon is not the same as a regular polygon.
How many rotational symmetry does a parallelogram have?
A general parallelogram has rotational symmetry of order two.
Can a figure have line symmetry and not rotational symmetry?
Yes. An ellipse (oval) has two lines of symmetry, but not a rotational symmetry. A parabola has one line and no rotation.
Can a figure with two or more lines of symmetry can have rotational symmetry?
Yes. A circle has infinitely many lines of symmetry and it also has rotational symmetry of infinite order.
What is the order of rotational symmetry of a rectangle?
Two.
A has two-fold rotational symmetry?
line
A line has rotational symmetry?
two-fold
What is the order of rotational symmetry does a rectangle have?
Two.
If a trapezoid has rotational symmetry what is the angle of rotation?
A "pure" trapezoid (a pair of parallel sides and two random sides) does not have rotational symmetry. If it is a parallelogram then it has a 180 degree symmetry. And if the paralloelogram happens to be a square, you have 90 deg symmetry.
What type of symmetry does a two fold line have?
It has rotational symmetry of order 2.
How man lines of symmetry and orders of rotational of symmetry does a Square have?
It have 4 axis of symmetry . Two Perpendiculars and two Diagonals
What is the order of rotational symmetry of a rhombus?
order two
