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.
A regular pentagon has rotational symmetry but does not have rational symmetry. Rational symmetry refers to the property of a shape that can be divided into equal parts by rotations that are fractions of a full rotation (e.g., 1/2, 1/3). Since a regular pentagon can only be rotated by 72 degrees (1/5 of a full rotation) to map onto itself, it does not exhibit rational symmetry.
A regular polygon with an order of rotational symmetry of 5 is a regular pentagon. This means that the pentagon can be rotated by multiples of 72 degrees (360 degrees divided by 5) and still look the same. Each of its five sides and angles is equal, contributing to this symmetrical property.
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
