What are dilations, similarity and scale factors - YouTube.
Dilations. A dilation stretches or shrinks a figure. The image created by a dilation is similar to the original figure. The scale factor of a dilation is the ratio of corresponding side lengths. In this course, the center of dilation will always be the origin. Dilation.
Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures. Lesson Opener and Goal Setting. Present the warm-up problem (5 minutes). The warm-up problem for this lesson (found in the slide show) asks students to find the equation for two variables from an x-y table. The relationship.

Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and dilations; given two similar two-dimensional figures, describe a sequence that exhibits the similarity between them.
Given a figure and a definition of a dilation, select or manually draw the image.

A similarity transformation, or similarity, is a composition of a finite number of basic rigid motions or dilations. The scale factor of a similarity transformation is the product of the scale factors of the dilations in the composition; if there are no dilations in the composition, the scale factor is defined to be 1.

This Dilation Transformation Lesson Plan is suitable for 7th - 12th Grade. Just how similar are dilations to isometries? The lesson builds upon pupils' knowledge of transformations and introduces the concept of dilations to obtain similar figures. Learners find out how to dilate a figure without the coordinate plane by using a straightedge and compass and with the coordinate plane by using a.

Notes on Dilations and Similarity Cluster 1: Understanding similarity in terms of transformations 5.1.1: Dilation with a center and scale factor, with a parallel line and a line segment 5.1.2: Transformations with similarity using equality of corresponding angles and proportionality of corresponding sides 5.1.3: Establish criterion of AA using similarity transformations A dilation is a.
Dilations Investigation-Student Activity. Objective: Given grid paper, a centimeter ruler, a protractor, and a sheet of patty paper the students will generate and apply the relationship between the scale factor of dilation and the coordinates of the image, angle measures.
