TRANSFORMATION RULES

Front

What is a transformation in geometry?

Back

A transformation in geometry is an operation that moves or changes a shape in some way to produce a new shape.

Front

What is a translation?

Back

A translation is a transformation that moves every point of a shape the same distance in the same direction.

Front

What is a reflection?

Back

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

Front

What is a rotation?

Back

A rotation is a transformation that turns a shape around a fixed point at a certain angle.

Front

What is dilation in geometry?

Back

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

Front

What does it mean to reflect a shape across the x-axis?

Back

Reflecting a shape across the x-axis means that each point of the shape is flipped over the x-axis, changing the sign of the y-coordinate.

Front

What does it mean to reflect a shape across the y-axis?

Back

Reflecting a shape across the y-axis means that each point of the shape is flipped over the y-axis, changing the sign of the x-coordinate.

Front

What is the result of a 90° clockwise rotation?

Back

A 90° clockwise rotation turns a shape 90 degrees to the right around a fixed point.

Front

What is the result of a 90° counterclockwise rotation?

Back

A 90° counterclockwise rotation turns a shape 90 degrees to the left around a fixed point.

Front

How do you identify a transformation from a shape to its image?

Back

To identify a transformation, compare the original shape and its image to see how points have moved, flipped, or rotated.
