1 2
2.) In the diagram, which triangle is the image of triangle 3 after a reflection over the x-axis?
3.) What transformation is represented by the figure below? 4.) Which transformation is represented by the figure below?
5.)Fill in the blanks:
The word congruent means both the same ____________ and ____________.
6.) Under which transformation can the image be a different size than the original figure?
7.) Which transformation means turning an object? 8.) Which transformation does not usually preserve size?
9.) Rotate the shape below 180° counterclockwise: 10.) Rotate the shape below 180° clockwise:
11.) Which two points represent a reflection of a point over the y-axis?
12.) If you translate the image three units up and one unit right, what are coordinates of the new image?
13.) What is the name of a figure after a transformation? 14.) If you rotate the rectangle below 180° clockwise about the origin, in which quadrant will the image lie?
15.) Which transformation is represented by the figure below? 16.) Write symbolically a translation 4 units left and 2 units up.

17.) If you translate the point (-5,3) four units right and 6 units down, which quadrant will the image lie?
18.) Write the rule (in words) for the translation of a point (3,-5) to the image (0,-4).
19.) If an image with the coordinates (2,5), (3,4) and (-1,0) is dilated using a scale factor of 3, what are the coordinates of the new image?
20.) The diagram shows a right triangle.
If the triangle is rotated 90° clockwise about the origin, what will the image be?
21) Graph and label triangle ABC, with coordinates A(-3,3), B(3,3), and C(6,-3). Next, draw the image of ABC after a
dilation with a scale factor of 13 . Label the image ABC. Next, draw the image of ABC after a translation of 4 units
right and 3 units down. Label the image ABC. Last, draw the image of ABC after a reflection over the x-axis. Label the image ABC.
