Transformation

Transformation
Transformation are the movement of figures from one location to another location. Transformations are just like transformers, they have a figure in a location and then into another location.
Translation
Translation is a movement of a figure from one place to another by sliding up, down, left, and right. Translation figures have to be congruent. If it's not congruent then the figures are not transformations.
Reflection
Reflection is a transformation where each point in a shape appears at an equal distance on the opposite side of a given line. Reflection is a mirror image of the original figure. Reflection has to be congruent too. A reflection is like a shadow too.
Rotation
Rotation is a transformation that turns the figure at a fixed point. Like all of the other transformations, rotation's figures have to be congruent. If it's not congruent and it doesn't turn at a fixed point then it's not a rotation. The fixed point at which a figure is rotated is called a centre of rotation.
Rotation of Figure
The blue dot is the centre rotation. It is easier to tell whether a figure is congruent, on grid paper.
Rotation of Figure
On this picture, the centre rotation is not on the figure, but close to it.
Rotation of Figure
In this picture, the figure is rotated and the centre rotation is inside the figures. The centre rotation point is the "C" point.
Congruent
Congruent figures have the same size and are the same shape. Two shapes are congruent if you can "Turn, Flip, or Slide" the figure and fit the exactly as the other.
Congruency
These two shapes are the same size and same shape.
Congruency
These angles are them same because you just have to flip it then then the two angles will match exactly the same.
