Are the two figures are congruent? Identify the rigid motions used.

• Yes, the figures are congruent. The rigid motions consist of a reflection followed by a rotation.

• Yes the figures are congruent. The rigid motions consist of a reflection followed by a translation.

• No the figures are not congruent. The rigid motions consist of a translation followed by a rotation.

• Yes, the figures are congruent. The rigid motions consist of a translation followed by a reflection.

State a sequence of rigid motions that would map Quad QRST onto Quad PLKJ.

• A reflection over the x-axis followed by a reflection over the y-axis

• A rotation 180 degrees followed by a translation 2 units to the right

• A reflection over the y-axis followed by a translation 7 units down

• A reflection over the x-axis followed by a translation 6 units to the right and 3 units down
