What is the congruent side of RY?

When quadrilateral PRST is translated to create quadrilateral P'R'S'T', which statement is true?

• The side lengths of quadrilateral P'R'S'T' are twice the side lengths of quadrilateral PRST

• The angle measures of quadrilateral P'R'S'T' are equal to the corresponding angle measures of quadrilateral PRST

• The side lengths of quadrilateral P'R'S'T' are 9 units longer than side lengths of quadrilateral PRST

• The angle measures of quadrilateral P'R'S'T' are greater than the angle measures of quadrilateral PRST

Are the figures congruent? (What type of transformation is shown?)

• NOT Congruent (dilation)

• NOT Congruent (translation)

• Congruent (dilation)

• Congruent (translation)

Which statement is true about the transformation?

• The transformation preserves congruency and maintains orientation.

• The transformation preserves congruency and does not maintains orientation.

• The transformation does not preserves congruency but maintains orientation.

• The transformation does not preserves congruency or maintains orientation.
