How Do You Use a Graph to Reflect a Figure Over the Y-Axis?
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 y-axis) and make the calculations to flip the figure.

What is a Reflection?
There are many ways to transform geometric figures. This lesson will illustrate how to reflect figures over a line to get a mirror image of the figure. The teacher will draw three different reflections: one as reflected over the y-axis,...

Rotations
Turn the class around. Scholars define rotations of multiples of 90 degrees and create algebraic mappings for them. After an introduction to symmetry, pupils determine which letters of the alphabet have rotational and reflectional...

Recognizing Odd and Even Functions
This video gives a formal definition of odd and even functions, as well as, an intuitive feeling for how they are different. By looking at the graphs of both types of functions, Sal shows the reflection properties of both functions....

What is a Transformation?
A transformation is the process of changing the graph of a figure or a shape. The instructor introduces the four most common transformations: reflection, dilation, rotation, and translation. So watch as she draws the transformations on a...
