Rigid Motion Transformations

Front

What is a transformation that 'turns' a figure about a fixed point at a given angle and direction?

Back

Rotation

Front

What is the term for moving a figure from one location to another without changing its shape or orientation?

Back

Translation

Front

What type of transformation flips a figure over a line, creating a mirror image?

Back

Reflection

Front

What is the new ordered pair when the point (-3, 4) is reflected across the x-axis?

Back

(-3, -4)

Front

What do we call the original figure prior to a transformation?

Back

Pre-image

Front

What is the term for the distance and direction a figure moves during a translation?

Back

Vector

Front

What is the result of applying a rotation of 90 degrees clockwise to the point (2, 3)?

Back

(3, -2)

Front

What is the effect of reflecting a point across the y-axis?

Back

The x-coordinate changes sign, while the y-coordinate remains the same.

Front

What is the term for the fixed point around which a rotation occurs?

Back

Center of rotation

Front

How do you determine if two figures are congruent after a transformation?

Back

They must have the same shape and size.
