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.
What shape has a two-fold rotational symmetry?
A shape with two-fold rotational symmetry looks the same after a rotation of 180 degrees. An example of this is a rectangle, which appears unchanged when rotated halfway around its center. Other shapes, like certain types of isosceles triangles and some polygons, also exhibit this symmetry. Essentially, any shape that can be flipped upside down and still match its original appearance has two-fold rotational symmetry.
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
What is the order of rotational symmetry does a rectangle have?
Two.
A line has rotational symmetry?
two-fold
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
