3. Which of the transformations below results in a mirror image?
Incorrect – dilations make the shapes larger or smaller
dilation
Incorrect – glide reflections are a type of transformation
glide reflection
reflection
translation
Incorrect – translations slide and orientation remains the same

4. The graph to the right shows a reflection over the:
x-axis
Incorrect – the x-axis is above both shapes. The y-axis is the line of reflection.
y-axis

5. Select the graph that shows a reflection over the x-axis:
Incorrect – This graph shows a rotation.
Incorrect – This graph shows a translation.

6. Assignment: Access the graphs for the assignment here.
Use Desmos to show the reflection of one graph. (Take a screen shot.)
Use ScreenChomp to show the reflection of a different graph. (Take a screen shot.)
Use graph paper and colored pencils to show the reflections of the final graph.

8. A rotation is a “spinning” about a fixed point, by a degree measurement.
true
false
Incorrect – rotation occurs by moving the shape counterclockwise around a single point

9. The graph to the right shows a rotation of:
90̊
Incorrect – a 90̊ rotation would be put the new shape in quadrant IV
Incorrect – a 270̊ rotation would be put the new shape in quadrant II
180̊
270̊

10. Select the graph that shows a rotation about the origin:
Incorrect – This graph shows a reflection.
Incorrect – This graph shows a translation.

11. Assignment: Access the graphs for the assignment here.
Use Desmos to show the rotation of one graph. (Take a screen shot.)
Use ScreenChomp to show the rotation of a different graph. (Take a screen shot.)
Use graph paper and colored pencils to show the rotation of the final graph.

13. Translations are the result of what movement(s)?
Incorrect – reflections result in mirror images
mirror image
spinning
Incorrect – rotations are a result of spinning
multiple moves
Incorrect – transformations are a result of multiple moves
sliding

14. The graph to the right shows a translation:
to the right 4 units
Incorrect – remember to count from A to A’, or B to B’, of C to C’
to the right 7 units
to the left 7 units
Incorrect – remember the original figure is named, the new figure is the prime

15. Select the graph that shows a translation:
Incorrect – This graph shows a rotation.
Incorrect – This graph shows a reflection.

16. Assignment: Access the graphs for the assignment here.
Use Desmos to show the translation of one graph. (Take a screen shot.)
Use ScreenChomp to show the translation of a different graph. (Take a screen shot.)
Use graph paper and colored pencils to show the translation of the final graph.

18. A transformation includes on and only one movement.
true
Incorrect – translations can be one or more movements
false

19. translated down, then reflected
The graph to the right shows a rotation of 180̊; it could also be transformed using which series:
translated down, then reflected
Incorrect – this would work, but it is not the best answer
Incorrect – this would work, but it is not the best answer
reflected, then translated down
both would work

20. Select the graph that shows a transformation that reflects over the x-axis and the y-axis.
Incorrect – This transformation is translated down six units, then reflected over the y-axis.
Incorrect – This transformation is translated to up three units, then left five units.
