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.
How do you measure the angles of incidence and reflection?
They are the angles made by the incident ray and the reflected ray with the line perpendicular to the reflecting surface at the point of reflection.
If the y-axis is the reflecting line and A is -1 2 its reflection image is A' equals?
A' = (-1, -2)
What does reflecting a shape mean?
Reflecting a shape means creating a mirror image of the original shape by flipping it over a line called the reflection axis. This results in an image that is an exact copy of the original, but in the opposite direction. The reflection axis serves as the line of symmetry between the original shape and its reflection.
How does a mirror produce an image?
A mirror produces an image by reflecting light. When light rays hit the mirror's surface, they bounce off at an equal angle of incidence. This reflection creates a virtual image that appears to be located behind the mirror.
How does image produce an image?
The light reflecting off of it in your line of site
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.
What is line halfway between the preimage and reflected image?
Line of reflection.
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.

How do you measure the angles of incidence and reflection?
They are the angles made by the incident ray and the reflected ray with the line perpendicular to the reflecting surface at the point of reflection.
What is a mirrior line?
It is a line of symmetry or a reflection on the Cartesian plane that produces a mirror image.
What are examples of glide reflections?
Examples of glide reflections include sliding a shape along a line while also reflecting it across that line. For instance, sliding and reflecting a triangle across a mirror line simultaneously creates a glide reflection. Another example could involve sliding and reflecting a letter along a surface, resulting in a glide reflection transformation.
