What is a Translation?
A translation means moving a figure to another location by sliding it. The figure, called the image, maintains its size and shape. You can move the image horizontally, vertically, or a combination of both.

What is a Rotation?
Transformations, isn't that geometry? The instructor illustrates how to rotate a shape around a fixed point on a graph, keeping the shape the same size.

How Do You Make a Figure Larger Using a Dilation?
A dilation increases or decreases the size of a figure. In this lesson the teacher shows you how to use a scale factor of three to dilate the given figure. She identifies the ordered pairs, multiplies them by three, plots the new...

How Do You Use a Graph to Translate a Figure Vertically?
Transformations. Learn a little bit of geometry. See how to translate a geometric figure on a coordinate plane vertically by sliding it over. Simply pick a point on the figure and count the units you want to move it. Then repeat that for...

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.
