Translation, Reflection, Rotation Test Flashcards

Front

preserves

Back

to keep something in its original state or condition

Front

plane

Back

a flat, two-dimensional surface that extends infinitely far.

Front

transformation

Back

A general term for four specific ways to manipulate the shape and position of a point, line, or shape.

The four ways are translation, reflection, rotation, and dilation.

Front

rigid motion transformation

Back

A transformation that preserves side lengths and angle measures.

Objects keep congruency with rigid motion transformation.

Front

pre-image

Back

The original figure before a transformation.

Front

image

Back

The resulting figure after a transformation.

The notation used with image is ' (prime notation)

Front

translation

Back

 a transformation that moves each point of a figure the same distance and direction.

Front

reflection

Back

A transformation representing a flip of a figure over a line, creating a mirror image.

Front

Line of Reflection

Back

The line over which a figure is reflected.

Front

Rotation

Back

A transformation that turns a figure about a fixed point at a certain angle.
