Understand similarity in terms of similarity transformations.

G-SRT.A.1Verify experimentally the properties of dilations given by a center and a scale factor:G-SRT.A.2Given 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.G-SRT.A.3Use the properties of similarity transformations to establish the Angle-Angle (AA) criterion for two triangles to be similar.
