Flashcard RETAKE: Rigid Transformations

Front

What are the three types of rigid transformations?

Back

Translations, rotations, and reflections.

Front

When a point (x, y) is translated 4 units left, what is the new position?

Back

(x - 4, y)

Front

What is the effect of translating a point 9 units right and 3 units down in algebraic notation?

Back

(x, y) --> (x + 9, y - 3)

Front

What is the term used for a transformation that turns a figure around a fixed point?

Back

Rotation

Front

In a reflection, what is the relationship between the original shape and its image?

Back

The image is a mirror image of the original shape across a line of reflection.

Front

What is the line called that acts as a mirror in a reflection?

Back

Line of reflection.

Front

How does a translation affect the coordinates of a shape?

Back

It shifts the shape without changing its size or orientation.

Front

What is the difference between a rotation and a reflection?

Back

A rotation turns a shape around a point, while a reflection flips it over a line.

Front

What is the angle of rotation in a 90-degree clockwise rotation?

Back

The figure is turned 90 degrees in the clockwise direction around a fixed point.

Front

What happens to the coordinates of a point (x, y) when it is reflected over the x-axis?

Back

The new coordinates are (x, -y).
