![]() ![]() Translation Shapes are slid across the plane. Chapter 4: Transformations Geometry Student Notes 13 Example 4 Does the figure have rotational symmetry If so, describe any rotations that map the figure onto itself. Reflection Shapes are flipped across an imaginary line to make mirror images. Find a point on the line of reflection that creates a minimum distance. A rotation is called a rigid transformation or isometry because the image is the same size and shape as the pre-image. Like restricted game pieces on a game board, you can move two-dimensional shapes in only three ways: Rotation Shapes are rotated or turned around an axis.Determine the number of lines of symmetry.You can compose any transformations, but here are some of the most common compositions: A glide reflection is a composition of a reflection and a translation. Compositions can always be written as one rule. Describe the reflection by finding the line of reflection. A composition (of transformations) is when more than one transformation is performed on a figure.Where should you park the car minimize the distance you both will have to walk? You need to go to the grocery store and your friend needs to go to the flower shop. A rotation is an example of a transformation where a figure is rotated about a specific point (called the center of rotation), a certain number of degrees. ![]() Now we all know that the shortest distance between any two points is a straight line, but what would happen if you need to go to two different places?įor example, imagine you and your friend are traveling together in a car. In geometry, a transformation is an operation that moves, flips, or changes a shape to create a new shape. And did you know that reflections are used to help us find minimum distances? ![]()
