The line of reflection A reflection is a transformation that acts like a mirror: It swaps all pairs of points that are on exactly opposite sides of the line of reflection. The line of reflection can be …
Reflections review (article) - Khan Academy
A reflection is a type of transformation that takes each point in a figure and reflects it over a line. This reflection maps A B C onto the blue triangle over the gold line of reflection. The result is a …
Reflecting shapes (video) | Reflections | Khan Academy
We have constructed the reflection of ABCD across the X axis. And what's interesting about this example is that, the original quadrilateral is on top of the X axis.
Reflecting points (video) | Reflections | Khan Academy
So here we're asked plot the image of point B under a reflection across the x-axis. Alright, so this is point B, and we're going to reflect it across the x-axis right over here.
Reflect points (practice) | Reflections | Khan Academy
Given a point and a definition of a horizontal or vertical reflection, plot the reflection on a coordinate plane or identify the coordinates of the reflected point.
Determining reflections (video) | Khan Academy
A line of reflection is an imaginary line that flips one shape onto another. We find this line by finding the halfway points between matching points on the source and image triangles.

In this topic you will learn about the most useful math concept for creating video game graphics: geometric transformations, specifically translations, rotations, reflections, and dilations.
Determining reflections (advanced) (video) | Khan Academy
Use the center of reflection to calculate the distance between the given point and the center. Reflect the point across the center using the distance and direction.
