Which of these sequences of transformations would return a shape to its original position?

• A. Reflecting over the x-axis, then reflecting over the y-axis

• B. Rotating 90 degrees clockwise around a point, then rotating another 90 degrees

• C. Translating 5 units up and 3 units to the right, then translating 3 units to the left and 5 units down

• D. Translating 3 units to the right then reflecting over the x-axis

CCSS.HSG.CO.A.5

How could you prove that these polygons are congruent?

• Rotate the figure 180 degrees, then translate it down 5 spaces.

• Reflect the original figure of a line, then dilate the figure.

• The Figure will not be congruent because it is corresponding.

• See if corresponding angles and portions are congruent and the shape. We could measure the figure or use trace paper to do this.
