A B 35 ° X K R Lesson 10-5: Transformations * Dilations A dilation is a transformation which changes the size of a figure but not its shape. This is called a similarity transformation. Since a dilation changes figures proportionately, it has a scale factor k. If the absolute value of k is greater than 1, the dilation is an enlargement. Notes Dilation A dilation is a proportional enlargement or reduction of a figure through a point called the center of dilation. The size of the enlargement or reduction is called the scale factor of the dilation. If the dilated image is larger than the original figure, then the scale factor 1. This is called an enlargement. www.harlem122.org This product involves four pages of interactive notes on translations, dilations, rotations and reflections.

Find the length of the resulting line segment A'B'. Show your work. B. Find the length of A'B' after a dilation centered at the origin with a scale factor of 3. A dilation is a type of transformation that changes the size of the image. The scale factor, sometimes called the scalar factor, measures how much larger or smaller the image is. Below is a picture of each type of dilation (one that gets larger and one that gest smaller). Example 1. The picture below shows a dilation with a scale factor of 2. Advanced Geometry LT 5.2 – Dilations Practice Find the scale factor from Figure A to Figure B and the center of dilation for each figure. 1. 2.

Joanne and Christopher are designing a quilt. They start by creating a triangle shape in the lower left quadrant as shown below. They transform it by rotating the triangle shown above 90 clockwise about the origin. Use the interactive transformation tool to perform dilations.

Precal Matters Notes 2.4: Parent Functions & Transformations Page 4 of 7 As you work through more and more examples, the shift transformations will become very intuitive. Dilations, however, can be tricky to interpret and tricky to graph, especially since several algebra texts do a poor job of describing what these transformations actually do. Note, this doesn’t work if the center is not the origin. a) In a dilation, the preimage point, image point, and the center point of dilation should all be collinear. Verify this above. b) In a dilation, the slope of each segment is maintained after the dilation.

Dilation changes the size of the shape without changing the shape. DILATION When you go to the eye doctor, they dilate you eyes. Let’s try it by turning off the lights. When you enlarge a photograph or use a copy machine to reduce a map, you are making dilations. Now use point N as the center of a dilation to locate the vertices of a triangle that has side lengths that are one-half the length of the sides of AABC. 3. Label the vertices in the two triangles you created in the diagram above. Based on this diagram, write several proportionality statements you believe are true. ***Notes on Dilations with a Center at the Origin Dilations Versus Stretches Versus Shrinks A dilation affects the x and the y value.

Thanks :) Reply Delete 7.0 Dilations Notes.notebook January 03, 2017 DILATION: A transformation that produces an image which is the exact same shape as the pre-image, but not the same size. Dilations Dilation (Similarity transformation) - transformation in which the lines connecting every point with its image point all intersect at a point called the center of dilation. The scale factor (k) of a dilation is the ratio of a linear measurement of the image to a corresponding measurement of the preimage. This is not a rigid motion. Translation: a “slide” of the figure -every point shifts the same distance, in the same direction. 1. a. On the graph, draw and label δABC, whose vertices have the coordinates A(1 , 1), B(6 , 2), and C(4 , 4).
