Back

Front

What does a scale factor less than 1 indicate in a dilation?

Back

A scale factor less than 1 indicates a reduction.

What does a scale factor greater than 1 indicate in a dilation?

Back

A scale factor greater than 1 indicates an enlargement.

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 a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point at a specified angle.

Front

What is a translation in geometry?

Back

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

Front

What is a congruence transformation?

Back

A congruence transformation is a transformation that preserves the shape and size of a figure, such as reflections, rotations, and translations.

Front

How do you describe a transformation that maps a triangle onto another triangle?

Back

You can describe it by identifying the type of transformation (reflection, rotation, translation) and the specific parameters (angle, direction, line of reflection).

Front

What is the effect of a 180-degree rotation about the origin?

Back

A 180-degree rotation about the origin flips the figure to the opposite side of the origin.

Front

What is the effect of a reflection in the line y = x?

Back

A reflection in the line y = x swaps the x and y coordinates of each point.
