In medieval times, a person was rewarded with a coat of arms in recognition of noble acts. In
honor of your noble acts so far in this course, you are being rewarded with a coat of arms. Each
symbol on the coordinate plane below represents a special meaning in the history of coat of arms.
Transform the figures from their original positions to their intended positions on the shield using
the following descriptions.
The chevron in Quadrant 1 stands for insight and intelligence.
1. Rotate the chevron 90º counterclockwise. Sketch the image of the chevron on the shield.
2. Write the symbolic representation of the chevron’s rotation.
The star in Quadrant II represents the steadfastness you have exhibited in completing your daily
math work.
3. Reflect the star over the x-axis. Sketch the image of the star on the shield.
4. Write the symbolic representation of the chevron’s reflection.
The claw in Quadrant III represents your persistence in pursuing algebraic solutions.

5. Sketch the translation of the claw on the shield given the symbolic representation x , y à
(x + 11, y + 9)
6. Write a verbal description of the translation.
The V-shape in Quadrant IV represents your victory over any fear or anxiety about math. The
location of the V-shape is determined by a composition of transformations as described below.
•
Rotate the V-shape 90º clockwise about the origin.
•
Reflect that image over the y-axis.
A coordinate grid has been provided to help with the composition of these transformations.
7. Complete the table by listing the coordinates of
the image after the V-shape is rotated 90º
clockwise about the origin and reflected over the
y-axis.
8. Sketch the final image of the V-shape after both
transformations on the shield.

9. Explain why each of the symbols on your coat of arms is congruent to the preimage of the
symbol on the original coordinate plane.
