G-SRT.1 – Verify experimentally the properties of dilations given by a center and a scale factor: a. A
dilation takes a line not passing through the center of the dilation to a parallel line, and leaves a line
passing through the center unchanged. b. The dilation of a line segment is longer or shorter in the ratio
give y 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 corresponding pairs of angles and the proportionality of all corresponding pairs of
sides.
G-SRT.3 – Use the properties of similarity transformations to establish the AA criterion for two
triangles to be similar.
G-SRT.4 – Prove theorems about triangles. Theorems include: a line parallel to one side of a triangle
divides the other two proportionally, and conversely; the Pythagorean Theorem proved using triangle
similarity.
G-SRT.5 – Use congruence and similarity criteria for triangles to solve problems and to prove
relationships in geometric figures.
