Reflect a figure in the x-axis | 8.G.A.3

9th - 12th
In this math video we will reflect a figure in the x-axis. We will identify the line of reflection first. We will understand that a reflection is a "flip" over the line of reflection. Each vertex of the figure must be reflected over the...

Identify a Reflection in the y-axis | 8.G.A.3

9th - 12th
In this math video we will identify a reflection in the y-axis. We will begin by identifying the line of reflection. We will understand that every vertex must be reflected the same distance over the line of reflection. We will reflect...

How Do You Use a Graph to Reflect a Figure Over the X-Axis?

6th - 12th
A reflection is just what you think it is, a mirror image. So how do you reflect a figure on a graph? Just flip it over. The teacher illustrates how to select a line of reflection (the x-axis) and make the calculations to flip the figure.

What is a Line of Reflection?

8th - 11th
Line of reflection is basically a geometry term used in the transformation of figures. It identifies the line on the graph that you reflect a figure over. The line can be vertical, horizontal, and diagonal. Actually, it can be any line...
