Effect of translation on perimeter.

• Translation increases the perimeter of a figure.

• Translation decreases the perimeter of a figure.

• Translation does not change the perimeter of a figure.

• Translation alters the shape of the figure, affecting the perimeter.

Definition of a scale factor less than 1.

• A reduction in size of the original figure.

• An increase in size of the original figure.

• A transformation that maintains the original size.

• A change in color of the original figure.

• 90 degrees

• 60 degrees

Transversal line.

• A line that passes through two lines in the same plane at two distinct points.

• A line that is parallel to another line.

• A line that intersects two or more lines at the same point.

• A line that is perpendicular to another line.

Scale factor in dilation.

• The ratio of any two corresponding lengths in two similar geometric figures.

• The difference between the lengths of two similar figures.

• The sum of the lengths of two corresponding sides in similar figures.

• The average length of all sides in a geometric figure.
