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.

In what way does a reflection preserve congruence?

• A reflection preserves congruence by changing the size of the original figure.

• A reflection preserves congruence by maintaining the same shape and size of the original figure.

• A reflection preserves congruence by altering the shape of the original figure.

• A reflection preserves congruence by rotating the original figure.

Determine if the two figures are congruent by using transformation. If so, what kind of transformation?

• congruent; a counterclockwise rotation of 90 degrees followed by a translation

• congruent; reflection

• congruent; translation

• not congruent

What is the difference between a transformation that preserves congruence and one that does not?

• The difference is in the color of the transformed figure

• The difference is in the number of vertices of the transformed figure

• The difference is in the orientation of the transformed figure

• The difference lies in whether the transformation maintains the shape and size of the original figure or not.

Which set of transformations could be applied to figure A to map it onto A'?

• reflect over y-axis, then translate down 2 units

• reflect over y-axis, then translate down 6 units

• rotate 180º about the origin, then reflect over x-axis

• rotate 90º CW about the origin, then relfect over x-axisfl
