A point or a line segment can be a preimage of itself because a line can be reflected or rotated.
a square,circle,pentagon
Well, honey, when we talk about the orientation of an image compared to the preimage, we're looking at whether the image is flipped, turned, or stayed the same. If the image is flipped, we call it a reflection; if it's turned, we call it a rotation. And if it stayed the same, well, that's just boring old identity. So, in a nutshell, the orientation can change through reflection or rotation, or it can stay the same.
This is the definition of "rotational symmetry", or if the statement is true for any number of degrees of rotation it is also "circular symmetry.".
To make a 10-sided regular polygon: I recommend you do 1 and 2 in pencil, and 3 in pen, you can always erase. 1- Draw a pentagon (five sided polygon). 2- Draw a pentagon just like the one you just made, rotated 180º (upside down) on top of the other pentagon (the center must be in the same place). 3- Connect adjacent (nearby) points of the two pentagons with straight lines.
No, they can be flipped and rotated.
counterclockwise
I rotated my petri dish so i could view it better.
THE LINE REMAINS PARELL ONLY IF ROTATED IN 180
A figure that has rotational symmetry but not line symmetry is a figure that can be rotated by a certain angle and still look the same, but cannot be reflected across a line to create a mirror image of itself. An example of such a figure is a regular pentagon, which has rotational symmetry of 72 degrees but does not have any lines of symmetry. This means that if you rotate a regular pentagon by 72 degrees, it will look the same, but you cannot reflect it across any line to create a mirror image.
Yes, the XLR connector can be rotated and locked into position
