Exploring Rigid Motion Transformations in 8th Grade Math

What does a translation in geometry involve?

• Rotating a shape around a fixed point

• Flipping a shape over a line

• Changing the size of a shape

• Sliding a shape a certain distance in a specific direction

What does the term 'rigid motion transformation' imply?

• The shape changes its form

• The shape's size and form remain unchanged

• The shape decreases in size

• The shape increases in size

What does it mean if two figures are congruent?

• They have different shapes but the same size

• They are mirror images of each other

• They have the same shape and size

• They have the same shape but different sizes

What is the difference between congruent and similar figures?

• Congruent figures are mirror images, while similar figures are not.

• There is no difference; they are the same.

• Congruent figures only share the same size, while similar figures have the same shape.

• Congruent figures have the same shape and size, while similar figures only share the same shape.

What is the term used for the original shape before transformation?

• Mirror

• Post-image

• Pre-image

• Image

How is a reflection performed in geometry?

• By rotating a shape around a center point

• By flipping a shape over a line

• By sliding a shape along a plane

• By changing the size of a shape

What does the 'prime' notation (e.g., A') signify in geometry?

• The point is a line of reflection

• The point has undergone a transformation

• The point is a center of rotation

• The point has not been moved

What information is needed to perform a rotation?

• A direction, angle of rotation, and a center point

• A distance and direction to slide

• An axis to flip over

• A line of reflection

In a rotation, moving a shape 90 degrees counterclockwise is the same as moving it how many degrees clockwise?

• 90 degrees

• 360 degrees

• 180 degrees

• 270 degrees

What does the line segment symbol over two letters (e.g., AB) represent?

• A reflection line

• A rotation

• A side of a shape

• An angle
