Front

What is a line of symmetry?

Back

A line of symmetry is a line that divides a figure into two identical parts, where each corresponding point is the same distance from that line.

Front

What transformation is described as moving a figure without changing its shape or size?

Back

Translation.

Front

What does it mean for two figures to be congruent?

Back

Congruent figures have the same size and same shape.

Front

What is the coordinate rule for a 90° counterclockwise rotation?

Back

(-y, x).

Front

What transformation occurs when a figure is flipped over a line?

Back

Reflection.

Front

How do you describe a translation of a figure?

Back

A translation moves a figure a certain distance in a specified direction.

Front

What is the result of reflecting a point across the x-axis?

Back

The y-coordinate of the point changes sign.

Front

What is the result of reflecting a point across the y-axis?

Back

The x-coordinate of the point changes sign.

Front

What does dilation do to a figure?

Back

Dilation changes the size of a figure but keeps its shape the same.

Front

What is the difference between rotation and reflection?

Back

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