Let's now consider another way to solve this exercise. We can find another sequence of rigid motions between the figures by applying transformations on the red figure. We will start by translating the red figure
4 units to the left.
Now, we will rotate the red figure
90∘ counterclockwise.
The two figures are in the same quadrant. Finally, we will move the red figure
1 unit to the left to get the blue figure.
Therefore, the sequence of rigid motions between the figures is
4 units to the left and a rotation of
90∘ counterclockwise, followed by a translation of
1 unit to the left.
