Dilation Scale Factors Similarity

A transformation in which all corresponding angles are congruent and all corresponding sides are in proportion.

• Dilation

• Reflection

• Rotation

• Translation

• Glide Transformation

If two polygons are similar, then the ratio of any two corresponding lengths in the polygons is ___________ the scale factor (or similarity ratio) of the similar polygons.

• equal to

• double

• triple

• the square of

• the square root of

A dilation in with the resulting image is larger than the original preimage. Scale factors must be greater than 1.

• Reduction

• Translation

• Enlargement

• Scaled Image

• Isometry

Two polygons with corresponding angles that are congruent and corresponding side lengths that are proportional.

• Corresponding Polygons

• Congruent Polygons

• Similar Polygons

• Transformed Polygons

• Isometric Polygons

If two polygons are similar, then the ratio of the lengths of two corresponding sides. Often referred to as k.
