Transformations Review

Translation (Math Shorts Video) You must watch the video for translations. A translation effects the... size of a figure. shape of a figure. position of a figure. If the figure below is translated using the following rule, what is A' ?(x+5, y-3) (-5, 5) (5, 3) (0, 2) (2, 0) Translation Notation Write the translation notation that slides JKL to J'K'L' (x-2, y-1) Which of the following transformations could nothave been created by a translation? Reflections (Math Shorts Video) Watch the video for a quick review of reflections (flips). A reflection effects the... size of a figure. shape of a figure. position of a figure. If the figure below is reflected across the x-axis, what is H' ? (-4, 5) (-4, -5) (5, -4) (-5, -4) Which of the following transformations could nothave been created by a reflection? Rotations (Math Shorts Video) Watch the video for a quick review of rotations (turn). A rotation effects the... size of a figure. shape of a figure. position of a figure. If the following figure is rotated 180° clockwise, which quadrant will the image be in? I II III IV If the following figure is rotated 90° clockwise, what is M' ? (2, -1) (-1, 2) (-2, -1) (-1, -2) Write your rules for rotations in the table. Use your Math Notes! 90 degree clockwise rotation (y, -x) 180 degree rotation (-x, -y) 270 degree clockwise rotation (-y, x) Which of the following transformations could nothave been created by a rotation? What is the difference between rotating 90° clockwise and 270° counterclockwise? Dilation (Math Shorts Video) Watch the video for a quick review of dilations (enlargments and reductions). A dilation effects the... size of a figure. shape of a figure. position of a figure. Which of the following scale factors would result in an enlargement? (You may select more than one) 2 1 3 1 4 2 1 5 Find the scale factor for this dilation. Be sure to look at the prime marks and simplify your answer! Which of the following transformations could nothave been created by a dilation? Which of the following transformations will change the size of the figure? Translation Reflection Rotation Dilation What is most likely the type of transformation that takes place from Figure 1 to Figure 2? Translation Reflection Rotation Dilation Match the term with its definition. Image The resulting polygon after the transformation Preimage The polygon before the transformation Scale Factor When a figure is dilated, it measures how much larger or smaller the image is Line of Reflection A figure is reflected over this to create a mirror image of the original figure Point of Rotation A figure is rotated around this point Which transformations does not change the size and shape of the original figure? (You may select more that one) Translation Reflection Rotation Dilation Which transformation results in a figure that is similar in size and shape? (You may select more that one) Translation Reflection Rotation Dilation
