Congruent Figures Transformations

Figure A is translated 3 units right and 2 units up. The translated figure is labeled figure B. Figure B is reflected over the x-axis. The reflected figure is labeled figure C. Which best explains why figure A is congruent to figure C?

Harley graphs a polygon that is located entirely inside quadrant I. He rotates the figure clockwise 90 degrees about the origin and then reflects the rotated figure over the x-axis. He translates the resulting figure 3 units to the left and 3 units up. Which best describes the location of the final image?

• quadrant I

• quadrant II

• above the x-axis

• left of the y-axis
