Dilation/Rotation Review

Master rotations and dilations! Geometry transformations practice for size, shape, and position.

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 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
