transformations that will carry a given figure onto another.

terms of rigid motions to decide if they are congruent.

congruent.


The dilation of a line segment is longer or shorter in the ratio given by the scale factor.
G-SRT.2. Given two figures, use the definition of similarity in terms of similarity transformations to decide if they are similar; explain using similarity transformations the meaning of similarity for
triangles as the equality of all corresponding pairs of angles and the proportionality of all corresponding pairs of sides.
