1. What is the definition of congruence?

• If two figures have the same shape, then they are congruent.

• 1. If two figures have the same area, then they are congruent.

• If there is a sequence of transformations taking one figure to another, then they are congruent.

• If there is a sequence of rotations, reflections, and translations that take one figure to the other, then they are congruent.

Which statement is true about a translation?

• A translation takes a line to a parallel line or itself.

• A translation takes a line to a perpendicular line.

• 1. A translation requires a center of translation.

• A translation requires a line of translation.
