Transformations and Congruency

Which type of transformation does not change the shape's orientation?

• translation

• reflection

• rotation

• none, they all change the shape's orientation

Which transformation(s) maintain congruency but not orientation?

• Translation

• Translation & Reflection

• Rotation

• Reflection & Rotation

Which representation of a transformation on a coordinate plane does NOT preserve congruence?

Translations keep

• both congruence and orientation

• only congruence

• only orientation

• neither

Dilations keep

• both congruence and orientation

• only congruence

• only orientation

• neither

Reflections keep

• both congruence and orientation

• only congruence

• only orientation

• neither
