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
What is true about corresponding line segments of an object that has been rotated 180 degrees about the origin?
The line segments will have been rotated by 180 degrees.
Does a paralleogram have rotational symmetry?
No, a parallelogram does not have rotational symmetry because it cannot be rotated onto itself. Rotational symmetry requires an object to look the same after being rotated by a certain angle.

What type of simple machine moves or turns an object?
A lever is a simple machine that can be used to move or turn an object. By applying a force at one end of the lever, the object at the other end can be lifted or rotated.
What are three ways that an object can be changed by a force?
The object can be moved in the direction of the force, changing its position. The object can be stretched or compressed, changing its shape or size. The object can be rotated, causing it to change its orientation.
What is the defenation of angular displacement?
Angular displacement is the angle in radians through which a point or line has been rotated in a specified sense about a specified axis. It is a measure of how far an object has rotated, typically measured from a reference point or axis.
What is the advantage of the parfocal lenses?
The advantage of a parfocal microscope=when different objective lenses are rotated, the object being examined will remain in view

Can a circle be changed into a sphere?
No. A circle is a 2-dimensional object a sphere is 3-d. However, a circle would generate a sphere if rotated about a diameter.

Do the couch cushions velcro on the bottom or can they be flipped and rotated?
No, they can be flipped and rotated.
