Transformations!

Front

What does it mean for translated figures to be congruent?

Back

Translated figures are congruent, meaning they have the same shape and size but may be in different positions.

Front

What is the effect of a 90° clockwise rotation on a triangle around the origin?

Back

A 90° clockwise rotation around the origin moves the triangle to a new position, changing its orientation.

Front

What happens to a figure during a 180° rotation around the origin?

Back

The figure is flipped upside down.

Front

How do you write a translation rule for moving a point?

Back

The translation rule can be written as (x + a, y + b), where 'a' and 'b' are the changes in the x and y coordinates, respectively.

Front

What is a reflection in geometry?

Back

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

Front

What is the difference between a translation and a rotation?

Back

A translation moves a figure without changing its orientation, while a rotation turns a figure around a point.

Front

What is the line of reflection?

Back

The line of reflection is the line over which a figure is reflected to create a mirror image.

Front

Can a figure be both rotated and translated?

Back

Yes, a figure can undergo multiple transformations, including both rotation and translation.

Front

What is the result of a reflection over the x-axis?

Back

The y-coordinates of the points in the figure are inverted, resulting in a mirror image across the x-axis.

Front

What is the rule for a reflection over the y-axis?

Back

The rule for a reflection over the y-axis is (x, -y), which inverts the x-coordinates.
