Dilations & Scale Factor
 All transformations in this test are Dilations.What is a Dilation?Dilationsred or blueenlarge or shrinkdog or cat Dilations are changes caused by scale factors.Dilated by a scale factor of 4 -->means •4243•4816 Dilated by scale factor of  ⅓---->  means multiply by ⅓.Note: Multiplying by ⅓ is the same as dividing by 3.241821• ⅓86 pre-image(2,6)Dilate a point by a scale factor of 5.x5x5multiply the x by 5multiply the y by 5(10,image) (4,-7)pre-imageDilate  by a scale factor of(image,3) (-9,-7)pre-imageDilate by a scale factor of(image4,) (8,10)Dilate by a scale factor ofpre-image(1/2image,) Dilate by a scale factor of (20,36)pre-image(1/4image,) Dilate by a scale factor of(8,-2)pre-image(6image,) Dilate by a scale factor of (24,42)pre-image(1/6image,) (-4,-7)pre-imageDilate by a scale factor of (image,2) Dilate by a scale factor of(-15,30)pre-image(1/5image,) 2-24-46-62-24-46-68-810-10B'A'C'(((,,,A)))BCDilate by k = 2 2-24-46-62-24-46-68-810-10Dilate by k =1/2B'A'C'(((,,,)))BAC 2-24-46-62-24-46-68-810-10B'A'C'(((,,,B)))ADilate by k = 3C 3 inDFE9 inD'F'Find the scale factor:(reduce)    PREIMAGEE'= 2-24-46-62-24-46-68-810-10   PREIMAGEFind the scale factor:(reduce)=TVV'T'R'S'RS Find the scale factor:Δ PSU is a dilation of Δ RST.8½16216{R8P8SUT TranslationRotationReflectionDilationIdentify transformation that maps ▲DOG to ▲D'O'G'. x-axisy-axisoriginΔD'O'G' is a reflection of ΔDOG.
