Geometry - Transformations Review

Front

What are translations, rotations, and reflections?

Back

They are types of transformations in geometry.

Front

In translations, how do the image and the pre-image relate to each other?

Back

They are always congruent.

Front

What is the transformation that occurs when an object is flipped over a line?

Back

Reflection.

Front

What happens to the coordinates (x, y) when translated 6 units up?

Back

The new coordinates become (x, y+6).

Front

What is a reflection across the y-axis?

Back

It is a transformation that flips a shape over the y-axis.

Front

What is the result of a 180-degree rotation?

Back

The shape is turned upside down.

Front

What is the difference between a translation and a reflection?

Back

A translation slides a shape without changing its orientation, while a reflection flips it over a line.

Front

If a point (3, 4) is reflected across the x-axis, what are the new coordinates?

Back

(3, -4).

Front

What does it mean for two shapes to be congruent?

Back

They have the same size and shape.

Front

How do you identify a translation on a graph?

Back

Look for a shape that has moved to a new location without changing its orientation.
