What are rotational symmetry?
Rotational symmetry is determining whether a shape has symmetry when it is rotated from the center. For example: if you have a star fish, it does have rotational symmetry because you can rotate the star fish 5 times and their still be symmetry. If the object has rotational symmetry, you then can determine the percentage and order of the ratational symmetry. The percentage is how much out of 100% the object is rotated to find symmetry. The order is how many times it is to be rotated before the object has returned to its origiinal position. Take the star fish example. It can be rotated 5 times (each turn having symmatry). The percentage of rotation would be 20%, and the order would be 5.
Is rotational symmetry is the quality a design has if it maintains all characteristics when its rotated about an axis lying in its plane?
Not exactly. Rotational symmetry means that a shape will look the same if the object is rotated around some axis, by ANY angle.There are no specific requirements as to where the axis must be.
How many types of symmetry are there?
There are several types of symmetry:rotational symmetry: an object maps exactly onto another if rotated about an axistranslational symmetry: an object maps exactly onto another if moved along a linereflective symmetry: an object maps exactly onto another if reflected along a lineand many combinations of the above, such as helical symmetry where an object maps exactly onto another if moved along a line and rotated about an axis.· Rotoreflection symmetry· Helical symmetry· Non-isometric symmetries· Scale symmetry and fractals
What is a rotational line of symmetry?
It is the axis of symmetry which is a line such that a object that is rotated at right angles to it becomes congruent to its original state before the angle of rotation reaches 360 degrees.
If a pair of parallel lines are rotated which is true?
THE LINE REMAINS PARELL ONLY IF ROTATED IN 180
