Preserve Congruence Transformations

Which transformation(s) maintain congruency but not orientation?

• Translation

• Translation & Reflection

• Rotation

• Reflection & Rotation

Translations keep

• both congruence and orientation

• only congruence

• only orientation

• neither

What is congruence?

• Same size, different shape

• Same size, same shape

• The way a figure is facing

• Flipping over a line

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

• translation

• reflection

• rotation

• none, they all change the shape's orientation

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

Reflections keep

• both congruence and orientation

• only congruence

• only orientation

• neither

A transformation is applied to create a new figure. Which transformation does not preserve congruence?

• A reflection across the x-axis

• A translation 4 units up

• A dilation by a scale factor of 5

• A rotation 90° counter clockwise

Tell whether the two figures are congruent.

• Yes, same size and same shape

• No, same shape but different sizes

• No, different size and different shapes

Congruent geometric figures have the:

• Same size

• Sides Equal

• Same Size and Same Shape

• Angles Equal

Which transformation does not preserve congruence?

• translation

• reflection

• rotation

• dilation
