Reflections are a type of transformation that move an entire curve such that its mirror image lies on the other side of the x or y axis.
A vertical reflection is given by the equation y=−f(x) and results in the curve being "reflected" across the x-axis. A horizontal reflection is given by the equation y=f(−x) and results in the curve being "reflected" across the y-axis.
Reflection is one of the four basic rigid motions.
Four basic rigid motions:
1.Reflection
2.Glide Reflection
3.Rotation
4.Translation
Answer with explanation:
→→→Reflection is done through a line.When you reflect an Object through a line the Pre-image before reflection and Image Obtained after reflection are congruent to one another.
Reflection is done through a line.
The equation of line can be
1. x=k
2. y=k
3.x +y=k
where, k is any real number.
→→→When you talk about rigid motion , then there are four kind of transformation that can take place in the object called Pre-Image which are
1.Translation
2.Dilation
3. Rotation
4. Reflection
Apart from dilation , in all other cases Pre-image and Image are congruent while in all cases the two are similar.
