Transformations on a Coordinate Plane

Translation (Math Shorts Video) Watch the video if you would like a quick review of translations (slides). A translation effects the... size of a figure. shape of a figure. position of a figure. location 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) Which of the following transformations could nothave been created by a translation? Reflections (Math Shorts Video) Watch the video if you would like 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 if you would like 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) Which of the following transformations could nothave been created by a rotation? Dilation (Math Shorts Video) Watch the video if you would like 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 Which of the following transformations could nothave been created by a dilation? If Quadrilateral QRST has points Q(4,1), R(-5,3), S(-4,3), T(-1,0), what would be the dilation if the new points are Q'(-1, 0.25), R'(-1.25, 0.75), S'(-1, 0.75). T'(-0.25,0)? 4 3 4 1 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. Translation A slide of the figure in which all the points on the figure move the same distance in the same direction Reflection Reflects a figure across a line in the plane Rotation A turn of the figure around a fixed point Dilation A transformation that changes the size of a figure by scale factor to create a similar figure 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 of the following rules would you follow to reflect an object across the y - axis? Change the value of y by multiplying by -1 Multiply both x and y by -1 Add or Subtract the x and y values. Change the value of x by multiplying by -1.
