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?

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.
