Rigid Transformations Review

Front

What are the three types of rigid transformations?

Back

A translation, a reflection, and a rotation.

Front

What is the resulting figure after a transformation called?

Back

Image.

Front

How do you translate a figure 5 units down and 4 units to the right?

Back

Move each point of the figure down 5 units and right 4 units.

Front

What is a translation in geometry?

Back

A transformation that moves every point of a figure the same distance in the same direction.

Front

What is a reflection in geometry?

Back

A transformation that flips a figure over a line, creating a mirror image.

Front

What is a rotation in geometry?

Back

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

Front

What does it mean for a transformation to be rigid?

Back

The shape and size of the figure do not change after the transformation.

Front

If triangle ABC is translated left 2 and up 9, what are the new coordinates of point A(3, 4)?

Back

A'(1, 13).

Front

What is the difference between a preimage and an image?

Back

A preimage is the original figure before transformation, while an image is the figure after transformation.

Front

What is an isometry?

Back

A transformation that preserves distances and angles, resulting in congruent figures.
