What is a reflection?

Back

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

What does rotation mean in geometry?

Back

Rotation is a transformation that turns a shape around a fixed point, called the center of rotation.

What is the effect of a reflection across the y-axis?

Back

A reflection across the y-axis flips the shape horizontally, changing the sign of the x-coordinates.

Front

What is the result of a translation followed by a reflection?

Back

The result is a shape that has been moved and then flipped over a line.

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.

What is a dilation in geometry?

Back

Dilation is a transformation that changes the size of a shape but keeps its proportions the same.
