How is a line of reflection like a line of symmetry?
A line of reflection and a line of symmetry both show the reverse of an image.
How are points and their images related to the line of reflection?
The line of reflection is the perpendicular bisector of any point and its image.
How can you find the line of reflection if you know the images of some points?
Draw a line joining a point and its image and find its midpoint. Repeat for another pair of point and its image. The line joining these midpoints is the line of reflection.
What is the difference between reflection and translation?
A reflection is when you "flip" an image over a line on your graph. A translation is when you move your image vertically and/or horizontally.
The composition of a translation and a reflection across a line parallel to the direction of translation?
Glide Reflection
What is the reflection image of (5 -3) across the line y -x?
It is (-3, 5).
What is the property of a figure that can be reflected across a line so that the image coincides with the pre image?
The property is Reflection Symmetry, Line Symmetry or Mirror Symmetry
How is a line of reflection like a line of symmetry?
A line of reflection and a line of symmetry both show the reverse of an image.
If the y-axis is the reflecting line and A is -1 2 its reflection image is A' equals?
A' = (-1, -2)
How are points and their images related to the line of reflection?
The line of reflection is the perpendicular bisector of any point and its image.
What is line halfway between the preimage and reflected image?
Line of reflection.
What are properties of reflections m?
Reflections in mathematics preserve the size and shape of the object being reflected. They also have the property that the reflected image is the same distance from the line of reflection as the original object. Additionally, reflections can be described by an axis of reflection, which serves as a line that the reflection occurs across.

A reflection is when you "flip" an image over a line on your graph. A translation is when you move your image vertically and/or horizontally.
What is the reflection image of 5 -3 across the y axis?
The y-axis is the symmetry line, so that (5, -3) and (-5, -3) are symmetric points.
The composition of a translation and a reflection across a line parallel to the direction of translation?
Glide Reflection
What is a mirrior line?
It is a line of symmetry or a reflection on the Cartesian plane that produces a mirror image.
