# How do i dilate a figure common core geometry transformations

CCSS, Rigid Motions, Dilations, etc. •The topic of transformations in geometry has fascinated some of us for a long time, but it has become a subject of wide interest right now because of the Common Core. •But transformations have been at the center of how mathematicians think about geometry for a long time. Represent transformations in the plane using, e.g., transparencies and geometry software; describe transformations as functions that take points in the plane as inputs and give other points as outputs. Compare transformations that preserve distance and angle to those that do not (e.g., translation versus horizontal stretch). G.9-12.CO.3 Let P', Q' and R' be the vertices of the translated figure. Since there is a translation of 7 units to the right and 5 units down, we have to add 7 to x-coordinate and subtract 5 from y-coordinate of each vertex. P' ------> (1+7, 11-5) = (8, 6) Q' ------> (1+7, 7-5) = (8, 2) Xribe at least two different transformations or sequences of transformations that xmsform square A to square B. 3 On the coordinate plane below, triangle ABC was rotated 180 degrees around the origin and then dilated by a factor of 2 with the center of dilation at the origin to form the green triangle, where x, y, and z represent the side lengths Of the green triangle. 123456 Complete the equality below by entering x, y, or z in the appropriate denominator. Rectangle ABCDplotted at A(4,2), B(8,2), C(8,8) and D(4,8) is to be reflected in the line x= 1 and then dilated by a scale factor of ½. (center of dilation is the origin). a)Plot the image of ABCDunder this sequence of transformations and label it A’B’C’D’.

COMMON CORE COMMON CORE HARDCOVER PAGES 77˜88 Turn to these pages to find this lesson in the hardcover student edition. ENGAGE Essential Question: How do you draw the image of a figure under a rotation? Possible answer: To draw the image of a figure The Common Core uses geometric transformations—dilation, reflection, rotation, and translation—to define congruence and similarity. In contrast, AoPS uses an informal definition of congruence and similarity that utilizes the students' intuition, saving transformations for later in the Introduction to Geometry course. Now, I have to figure out where to start in terms of the Common Core. After talking to our county math person, I think I am going to begin with what the Dana Center has for Algebra 1 and then adjusting for the PARCC Model Content Frameworks since we are in a PARCC state.

Many people don't like the reliance of Common Core Geometry on transformations. I like the idea that many statements that are postulates in pre-Core Geometry, such as SAS (both similarity and congruence), the slope formula, and so on, are provable in Common Core Geometry. Our common core aligned content covers a variety of standards defined by Common Core State Standard(CCSS) initiative. These standards establish a set of clear and consistent guildelines about what student are expected to master and be able to do in Mathematics and English Language Arts.
