Congruency and Orientation Rigid

What does it mean if two figures are congruent?

• The figures are the same shape, but different size

• The figures are different size and shape

Rigid Transformation mean...

• The shape's angles rotate 90° CCW.

• Lengths and angle measures are preserved

• A dilated image.

• Movement that adjusts the length of the sides, but not the angle measure.

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.

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

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.

The triangle FRG is rotated 90^o counter-clockwise. Which of the following statements is true. 

• The image maintains the preimage's orientation

• The image maintains the preimage's congruence

• The image maintains the preimage's orientation & congruence

• The image doesn't maintain the preimage's orientation or congruence

What is the definition of Rigid Motion

• a transformation

• the original figure and the figure after the transformation

• a special type of transformation that preserves the size and shape of the figure

• a mapping or movement of a plane and all points on that plane according to a common action or operation.
