when every part has a matching part
No A rectangle has rotational symmetry as well
Yes it does
Yes it does. As long as it has a symmetry without rotation. If you do the rotation either way it does have symmetry. :)
Asymmetrical
A square by definition has lines of symmetry. Therefore a square cannot be drawn without any lines of symmetry.
If it says rotated it's true If it says reflected it is false
False
Yes. Any even sided figure will have a rotational symmetry. Yes. If it is a regular shape such as a square, hexagon or octagon (equilateral and equiangular) then the rotational symmetry is the same as the number of sides. Rotational symmetry is basically if the shape is rotated, is it exactly the same as it was before. A hexagon can be rotated 6 times and still be the same without actually being in the the same postition, so a hexagon has a rotational symmetry of 6.
Essentially an ellipse is a circle rotated about an axis without changing the point of view.
The order of rotational symmetry for a shape is the number of times that it can be rotated so that it appears the same without rotation (e.g. if you rotate an equilateral triangle 60o clockwise it looks the same).For regular polygons, the order of rotational symmetry for the shape is the number of sides that it has. A hexagon has 6 sides so has order of rotational symmetry 6.

No. The number of protons is part of the fundamental characteristics of an element.
Yes it does
Yes it does. As long as it has a symmetry without rotation. If you do the rotation either way it does have symmetry. :)
you can not do it without an additional set of chips for changing the characteristics of the signal
