Retake 3-1 Rigid Motions

Front

What is a reflection in geometry?

Back

A type of transformation where a figure is 'flipped' over a line of symmetry.

Front

If point (-5,2) is reflected over the y-axis, what are the coordinates of the new point?

Back

(5,2)

Front

What transformation is described by moving a point 5 units left and 1 unit up?

Back

Translation 5 units left, 1 unit up.

Front

What is the angle of rotation for a 270° counterclockwise rotation about the origin?

Back

270°

Front

Describe the transformation represented by (x, y) → (x, -y).

Back

Reflection across the x-axis.

Front

What is a rotation in geometry?

Back

A transformation that turns a figure around a fixed point.

Front

What does a translation do to a figure?

Back

It moves the figure from one location to another without changing its shape or orientation.

Front

What is the line of symmetry in a reflection?

Back

The line over which a figure is flipped to create a mirror image.

Front

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

Back

(3,-4)

Front

What is the difference between a rotation and a reflection?

Back

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