I learned a bunch of things while watching these videos:
1. When doing a translation or rotation it is easier to move the figure point by point instead of moving the whole polygon.
2. When you label the points on your image, used an apostrophe, which is called “A prime”.
3. I learned to label the reflection line, use a cursive L, because if you use a regular L, it looks like a one.
4. I learned when doing a reflection, it is easiest to just count the distance (squares) from each point to the reflection line, and put the image point the same distance away on the other side of the reflection line.
5. I learned to look at all the instructions in a rotation which are the angle, the direction (clockwise or counter clockwise) and the “center of rotation”.
6. I like using tracing paper and using arrows for rotations. It makes rotations easier to understand.

ROTATIONAL SYMMETRY:I learned that is that rotational symmetry is how many times the figure fits its original shape when it turns.
LINES OF SYMMETRY:I learned that there is lines of symmetry in nature too.
TRANSFORMATIONS:translation is when you move a figure,rotation is wen you rotate a figure and reflection is when you reflect a figure using a mirroir.
For a rotation you can use tracing paper or you can draw a cross then find where the rotation is.

Transformations: I learned that every time you start with a new image you have to put a little line and that line means prime so it's not the same figure as the first one.
Rotational Symmetry: I leaned that if all of the sides on one image are the same length then the rotational symmetry is as many sides that it is. So for example: If you have a Hexagon then the rotational symmetry will be 6.
Lines of Symmetry: I learned that for lines of symmetry you can use a mirra as a manipulative to make sure that it has a line of symmetry.

Lines of symmetry: You can use a mirror to find if it would work.
Rotational symmetry : That if each side is equals it would end up as many sides there is as the rotational symmetry.
Translations : To start from a point instead the whole figure and to always remember to put prime.

Transformations:
When you do translations and reflections you can move point by point. Also, when doing a rotation you have to make sure you follow the steps given for the rotation.
Lines of symmetry:
You can use a mirra to find your lines of symmetry. A line of symmetry basically divides a shape in half so you can fold it over and it will match up exactly.
Rotational Symmetry:
You can use tracing paper to figure out what is the order of rotational symmetry. I learnt that in rotational symmetry you see how many times the shape coincides with itself and you do that by spinning the shape.

1.It is easier to move a figure point by point.
2.If you do a 180 degree turn its also a reflection.
3.If the figure has no rotational symmetry after 2 turns then it does'nt have any.
4.That the y axe comes befor the x.

1.I learned how to use tracing paper to rotate objects
2.I learned how to rotate figures with a grid easily
3.I learned how to figure out ratational symitry by seeing if the sides are congruent
4. Rotational symitry is how many times an object co insides with it self
5. That it is very easy to find lines of symitry because lines of symitry are just like a reflection line or a mira

1. When your doing a translation its easier to move point by point.
2. I learned to use tracing paper for rotations and put an arrow and think of it as a clock.
3. When you make a transformation you have to put prime which is the little line next to the letter.
4.Rotational symettry is how many times the figure can fit inside itself.
5. Tracing paper is also easier to do rotations instead on trying to rotate you get confused but with the tracing paper its way easier to do.

1.I learned that when doing a rotation using tracing paper is the easiest.
2. I learned that it is easier to move a figure point by point than the whole shape at once.
3.when doing a transformation you must put prime or ' to show that the shape is an image not the actual figure.
4.I learned that the x or horizontal axis comes before the y or vertical axis.
5.I learned that when you rotate a figure 180 degrees it does not matter if you rotate it clockwise and counter clockwise.
